As I have explained? a Dual Core is a combination of two independent processors? pending in a single package or a single circuit int? gr? (IC). A device? dual processor contains two independent microprocessors? pendant and a quad core device contains four microprocessors as well. The cores in a dual-core processors will share a cache coh?

For example, the higher-end chip Intel Pentium Extreme Edition 955chip, it has a higher speed of the FSB and a 2MB greater m? cache memory capacity and heart? ? use Hyperthreading. On the other hand AMD Soci? T?, Do not use the old mod? Of the FSB. They use a new technology that we call HyperTransport to communicate with the chipset and the m? Memory system?

With this new technology, AMD is arriv? ? the benefit of many, especially with the passage? dual-core processors. The last? Re g? No? Ration Core Solo AMD can use a single channel or m?

Section 7: Benefits The dual processors? the m? me fili? circuits have re coh? reference cache may operate en? clock frequency much? lev? what is possible if the signals must travel off-chip.

Multi-core technology will have a disruptive effect on your business
Tuesday, August 31st, 2010Imagine you have a factory with an assembler and a quality control (QA) engineer. Each element assembler churns through QA before being packaged for delivery. As you add other assemblers on the factory, you will reach the maximum effect of the QA engineer. Once you exceed that number, QA becomes the bottleneck. Fast forward to current IT practices. Most firms practice the concept of an application server. In a small business environment, this practice is acceptable, because usually you only have a handful of powerful servers all the computing needs of the business. The management is simple and straightforward. In large companies you have hundreds or thousands of operations staff located in several places. You application servers for financial support, logistics, human resources, production, purchasing, design and development. You also have your usual file and print servers, and several mail servers strategically located in the regions. IDC estimates that the dollar by buying a server, it will cost $ 7 to manage it. Your TCO is now running out of control with almost no hope in sight. To complicate matters, studies have shown that most applications do not exploit the resources of computer servers on which they run. The use varies from 5 to 10 percent depending on the application. Now you have the IOC requires a record of resources and better justification of the request for a new server to house the new application. Fortunately an old technology once available only on mainframe computers very expensive now found its place in the world of distributed UNIX and Windows. Virtualization allows you to create multiple virtual servers, which can host your applications. This raises the levels of use of existing servers and productivity increases because the establishment of a new server for a new application will take only a few hours instead of days or weeks. In addition to virtualization is a recent progress in the design and manufacture of microprocessors – multi-core. A multi-core microprocessor is one that combines two or more independent processors into a single package. For example, a dual-core device contains two independent microprocessors. With appropriate software, a multi-core processor can perform parallel execution of multiple software son. The operating system (OS) perceives each of its execution units as a discrete processor, with all the associated execution resources. By enabling enhanced performance and more efficient simultaneous processing of multiple tasks, multi-core processors promise to improve the user experience at home and business environments. Benefits of multi-core Martin Reynolds, vice president at Gartner, said that “the initiative will be multi-core performance in advance simpler than we saw in the PC processor. For applications that take advantage of it, you’ll a 50-60 percent better performance. We have not seen that since the initial transition to the Intel 80286 processor Intel386 processor. “ The multi-core processors allow you to perform computing tasks today in a more efficient and allow a whole new computing experience, and benefits for the server platforms and client, and home environments and company. ability to multi-core can improve the user experience in multitasking environments, where a number of leading applications coincides with a number of background applications such as virus protection and security, wireless , management, compression, encryption and synchronization. By multiplying the number of cores in the processor, you greatly increase the capabilities of PCs and computer resources, reflecting a move towards greater responsiveness, higher throughput multithreaded, and the benefits of parallel computing in consumer applications. In the digital company The steady increase in the density of systems in data centers is the creation of power and cooling challenges for many organizations. Part of the answer will be platform multi-core servers. By allowing a single processor form factor for use multiple processor cores, these platforms offer superior performance and scalability, while remaining relatively stable in energy consumption, heat and space. Consequently, greater processing capacity can be concentrated in fewer servers. This means greater density and number of servers to manage. Vice-president and general manager of IDC’s Enterprise Computing, Vernon Turner said that “when you quadruple the capacity of today’s servers with multi-core processors, you can run new workloads. Typical 4-Way Servers supports the work that previously required midrange or high-end symmetric multi-processing. Therefore, we will move complex business processes, databases, data mining, and the investigation and applications of intelligence data on industry standard servers, multi-core. In the Digital Office The multi-core processors hold the promise to support the considerable increase in computer performance seen in the last quarter century. What is the average performance of the office productivity? Designers, for example, can render images faster on multi-core. The greater responsiveness of platforms and multi-core means less waiting for everyone in the digital office. For stockbrokers, this could literally mean dollars, as their computers enable more informed investment decisions and faster trades. For mobile users Advances in wireless technology have made mobile computing in places we never dreamed. Today you will find a businessman working remotely in a cafe at the airport via Wi-Fi Added multi-core processors to the mobile composition to expand their horizons even more. Incredible new mobile technologies allow doctors to remotely diagnose cities of patients living in remote locations (for example). In 2006, we will see successful deployments of new PCs and servers that take advantage of the multi-core technology.

Digital watermarking technology and its applications security
Sunday, August 1st, 2010The use of numerical integration methods hidden in images, sounds, documents, books, videos and other digital products, to achieve the objective of the existence of hidden messages. HC screen Special Indian Network Digital Watermarking (tattoo digital) technology in recent years the rise of international information security community as subjects of advanced research, is close to the practical application of information hiding. Digital watermarking (Digitalwatermarking) technology in recent years the rise of international information security community as subjects of advanced research, is very close to the practical application of information hiding. With information security to hide information, data encryption Dengjun close. The watermarking algorithm through some tags have a special meaning (watermark), using numerical integration methods hidden in images, sounds, documents, books, videos and other digital products, to achieve the objective of the existence of hidden message, using the interests of the owner to prove ownership of their works, and the identification, pursuit of illegal violation of the evidence, while the watermark detection and analysis of reliability to ensure the integrity of digital information, making intellectual property protection and security digital multimedia and effective means of protection IP, confidentiality and communicate content identification fields have a wide range of applications. A digital watermark key composantesl’analyse digital watermarks in theory, based on rapid development in recent years wavelet (WaveletAnalysis) . watermarking technology is very robust to be seen, hidden place of safety, no ambiguity, and the computational efficiency and so on. Watermark embedding and extraction system is divided into two parts, each part of it by the software and hardware. This composition forms effectively improve the level of anti-counterfeiting technology, which greatly increases the difficulty of counterfeiting counterfeiting. Following features: (1) as a digital watermark identifier is not visible in the form of visual hide and printing products, natural light or artificial light irradiation, the naked eye can not distinguish whether Instead of adding a digital watermark printed marks and does not need to protect printing (bunker watermark), the original image of the visual senses, as by a computer or computerized machine reading device can determine . (2) print the watermark hidden in the tag is not just a place at random can be arbitrary, so that printing has played a role in multiple security. (3) print the watermark hidden in the tag does not change after the printing location, handling personnel and the time change in the link above does not leak and the possibility of proliferation. (4) to embed a watermark printed tag does not alter the appearance of the properties original print, not printing equipment being special needs, without changing the printed material, but not to increase the printing costs. The basis of modern security technology, trends , printed mark in the method of detection of digital watermarks using DSP chips and random access memory with machine-readable identifier. This high performance aircraft machine-readable identification is easy to mass production, and good product consistency, low cost, simple operation to use, reliable, to determine the authenticity of the software to run fast, strong and good, quick updates and so on. Secondly, the basic technology numérique1 watermark, wavelet Generation and hidden digital watermarking algorithm: wavelet algorithm, the digital image data in space by discrete wavelet transform (DWT ) in the corresponding wavelet coefficients, and the type of information to be hidden, the appropriate coding and its deformation, and then hide the amount of information depending on the size and corresponding security objectives, choose the place of frequency domain coefficient sequence. Finally, the image digital frequency domain coefficients by the inverse transform in the spatial domain data. 2 watermark technology anti-copy: counterfeiters get when printing with digital watermark and packaging, he will surely try to copy (such as high precision digital scanner), to prevent the watermark information is copied, the watermark hidden digital watermark information embedded software using chromatography equivalent for an algorithm given, this method can not guarantee and piracy in the adjustment process to respond to the colors of the original image, you can not avoid a similar change chromatography, so fundamental to ensure the watermark will not be copied. 3 , anti-fading technology: from digital images for print, pass the plate, printing processes such as multi-channel digital watermark on the characteristics of each process must be mitigated to ensure the final print watermarks enough signal strength, digital watermark embedding watermark information in the software generated fully taken into account a signal strong enough to ensure that through a number of process when the signal strength (strength) may still be reliable machine readable. 4 machine-readable digital watermark test: the test machine readable digital watermark technology eliminates the uncertainty of human factors to improve test speed and improve the hidden information (watermark) to identify security, and RFID can, UV, magnetic tape and other equipment safety inspection system was composed of mature multidimensional security, to improve the security level integrated. To develop a low cost, mass production can be industrialized as detector material type machine-readable digital watermark inspection machine reading devices should be used embedded operating system (Vix / Vox), with chip DSP processor core using the CMOS camera and face training (CCD) image sensor devices to form a portable and mobile air conditioners, and DC, can be networked, the software can quickly update the detection equipment in digital security.

Industry digital imaging technology: a breakthrough for China in the information
Saturday, July 31st, 2010The eighties of last century, China and Korea, and Taiwan region of China, at the same time start the development of the microelectronics industry. North Korea has established a focus on capturing the memory in the world semiconductor (memory) market strategy, the focus of China on Taiwan on the development of production processes of semi-conductors, s Relying on massive world dedicated chip (ASIC) market transformation. Over the past two decades, North Korea and Taiwan from China in the global microelectronics industry occupies an area and enter a virtuous circle of industry. The microelectronics industry in China mainland for various reasons, did not establish a long-term strategic development, focusing on capturing a given area, the results obtained so far also failed to structure the information in the world to take its place.Aujourd ‘hui, North Korea in the field of memory chips has unparalleled advantages, Taiwan of China in the chip manufacturing industry plays a vital role while that the United States in the PC central processing unit (CPU), and other various media processor (CPU) at the head of the world beyond the controversies. Now, people have formed a consensus to revive the Chinese microelectronics industry, it must be our country’s products and overall development strategies, the dumping of this country based on the capture of a force field. China has an urgent need percéeAprès two decades of development, the information industry of China has collected a considerable force, and gained considerable experience accumulated. We believe that the imperative is not only a question of capital and talent, but the key microelectronic technology products in many markets as soon as possible to get a costume from China to present technological level and production capacity but also a huge market potential in new areas, and as a breakthrough in the field and try to grasp the leading position in monde.Seulement this way can lead the information industry of the state and that the national economy. Deriving the fierce international competition to obtain and maintain a position leader.Le best of the four conditions necessary for percéeNous think the better should have a key breakthrough in the four following conditions: 1. The new technology – can be avoided by direct competition with existing products and markets, 2. The market is huge – huge profits available, and re-investment 3. maturity of the production process – can make use of the line production of China’s existing large-scale production, 4. A long cycle life of the product – a longer period can not be a lithograph produced on a smaller scale Sur. Judging by the current situation, we believe that these four conditions are the best choice of products is the technology digital imaging and products.The benefits of imaging technology numériqueNous talking about digital imaging technology, especially digital conversion of fingerprint technology CMOS, which is a pure digital imaging technology, that technology CCD conventional imaging, the main advantage is its low prix.Bien that CMOS chips to enhance the image quality of digital photos (currently 1. 3 million pixels) CCD chip (currently up to 5 million pixels ) slightly lower, but a CMOS chip, but its low cost and competitive price, using CMOS chip, you can create a much more affordable digital cameras, therefore, CMOS technology, more and more concern for designers of digital cameras come in handy in the industry numérique.puces CMOS camera, an important advantage is that the minimum energy consumption, therefore, CMOS image sensors for the growing market demand, often insuffisant.U number. S. Agency for the international market research (Dataquest) analysts believe that although the performance of CMOS chips is not the best, but it is cheap, which is the expansion of markets for digital cameras is essentielle.Technologie digital CMOS imaging device has matured, and compared to conventional imaging CCD, CMOS digital imaging system has the advantage of imaging system integrated into a single chip, enabling CMOS system with the amount of smaller, less space than smaller, less power and overall low prices and so on. It is estimated that the CMOS digital imaging devices have been able to reach 2 million pixels, which represents 30-40% of the camera market numériques.Marché applicationsDigital wide range of imaging chip market wide range of technology applications, mainly all kinds of video products, including computer cameras, digital cameras, digital cameras, video phones, all kinds of industrial, medical, transport and security and other areas of the camera or camera systems, and capturing images with a special function or electromagnetic sensor systems optiques.La digital imaging technology and markets with high growth potential is enormous. 30% annual growth rate is expected to flea digital imaging in 2005, 50 billion market, the growth rate reached 30%. digital imaging chip as a core component of the market potential of products is enormous, including: PC Camera: 2001 Turnover: 12 million units in 2005 should reach 100 million units. Digital Cameras : 2001 turnover of 18 million units, compared to 2000, growth of 55%. In 2005, reaches 50 million units. Printers, scanners, digital photo paper will also be a great développement.Autres enforcement tools: cell phones, e-mail reader, web tablet, Palm Pilot, smart phones, communication devices, mobile Internet is also widely used imaging technology numérique.Particulière should not overlook the potential market for mobile digital imaging, digital video mobile would grow at an annual rate of 400% of development, such as mobile phones, PDAs, etc.. It is estimated that by the end of 2002, Europe will be over one million customers through non-PC Internet access devices, mobile subscribers will reach 1 billion. In 2005, three quarters of Europeans have a mobile phone network, half of them will be for use régulière.2005, global handset production will reach 500 million. One third of the phone with a camera, text messages, multimedia messages, including musical entertainment from the text of static images and dynamic multimedia information is intended to be popular 2002.Il no hegemonic estNous have the opportunity deEst particularly noteworthy is that, compared to memory chips, CPU is a party to such a dominant product in the digital imaging chip, and has broad prospects in this field, always in a Melee crowded situation has not yet emerged hegemony. Currently, OmniVision, Kodak, Zoran, Motorola, IC Media, Surplus, Winbond and other famous big companies, and at least a dozen university laboratories are seriously committed to studying a digital camera chip CMOS approfondie.130 on behalf of multi-megapixel digital camera chips, there are individual companies in the development of 2 million pixel camera chip. However, no company can do as the CPU position of market dominance, it is history and the market will give us the opportunity, if we focus on financial, human, material seized in this as the capture North Korea zone of origin of memory chips, Taiwan, caught the field of chip manufacturing, as it is quite basic conditions possible.Intérieur Sonten particular, it should be noted that the chain of domestic industry has taken shape smart. After 20 years of development, China has been undertaking a self-developed integrated circuits, the introduction of improvement and focus on the construction of three major stages of development. Now a large industrial base, formed by seven companies that manufacture chips on the spine, more than a dozen packing plant, dozens of major design firms, and key materials and special equipment industry group composed of equipment manufacturers. IC design, wafer fabrication and packaging circuit three simultaneously presented relatively concentrated geographically tendance.production integrated circuit in 2000 of about 5. 88 billion, compared to 1999, an increase of 41. 7%, sales of nearly 20 billion yuans.Huahong 0. 35-micron chip production lines and thus launched, making China become the world center of chip manufacturing conditions, but also makes the mainland itself made up a chip design, production and packaging of industrielle.Du chain perspective of the market, the Chinese market for mobile telephony, the world’s largest market of PC is about to overtake Japan in second place in the world, the National Planning Commission, industry digital camera, a special plan for chip design, manufacturing provides a broad application prospects. Therefore, the current situation of China was that everything is ready, only a strong wind, the Dongfeng China is making stratégique.ConclusionEn summary, we believe that China should seize the historic opportunity to launch the digital imaging technology for national development strategies, the upper hand in the global information The occupation of land, thus giving impetus to the entire national economy, so China in the information industry to catch up and overtake the developed countries, and therefore in the foreground.
