This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The international Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 圖Figure 1.

DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image compression standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the international Organization for Standardization (ISO) and international Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.

The extraordinary growth of the World Wide Web has been fueled by the ability it gives authors to easily and cheaply distribute electronic documents to an international audience. As Web documents have become larger and more complex, however, Web content providers have begun to experience the limitations of a medium that does not provide the extensibility, structure, and data checking needed for large-scale commercial publishing. The ability of Java applets to embed powerful data manipulation capabilities in Web clients makes even clearer the limitations of current methods for the transmittal of document data.

DES( Data Encryption Standard)算法，于1977年得到美國政府的正式許可，是一種用56位密鑰來加密64位數(shù)據(jù)的方法。 IDEA是international Data Encryption Algorithm 的縮寫,是1990年由瑞士聯(lián)邦技術(shù)學(xué)院來學(xué)嘉X.J.Lai 和Massey提出的建議標(biāo)準(zhǔn)算法稱作PES( Proposed Encryption Standard) 。Lai 和Massey 在1992 年進(jìn)行了改進(jìn)強(qiáng)化了抗差分分析的能力改稱為IDEA 它也是對(duì)64bit大小的數(shù)據(jù)塊加密的分組加密算法密鑰長度為128位它基于“相異代數(shù)群上的混合運(yùn)算”設(shè)計(jì)思想算法用硬件和軟件實(shí)現(xiàn)都很容易且比DES在實(shí)現(xiàn)上快的多。IDEA自問世以來，已經(jīng)經(jīng)歷了大量的詳細(xì)審查，對(duì)密碼分析具有很強(qiáng)的抵抗能力，在多種商業(yè)產(chǎn)品中被使用。
