DDR SDRAM控制器的VHDL源代碼，含詳細(xì)設(shè)計(jì)文檔。 The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS), and Digital Frequency Synthesis (DFS) functions. This application note describes a controller design for a 16-bit DDR SDRAM. The application note and reference design are Enhanced versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz, 16-bit data changes at both clock edges. The reference design is fully synthesizable and achieves 133 MHz performance with automatic place and route tools.

這個(gè)軟件包(C++)是我尋找電磁學(xué)代碼無意中找到了，功能相當(dāng)強(qiáng)大（并行計(jì)算，快速多極子等）。缺點(diǎn)是安裝相當(dāng)麻煩，需要若干個(gè)其他軟件包。我在Fedora Core9下編譯其中所需blitz++時(shí)出錯(cuò)，在 ubuntu下可以所有均編譯通過，運(yùn)行時(shí)出現(xiàn)一個(gè)錯(cuò)誤，我找不到原因（本人水平有限），但從學(xué)習(xí)電磁學(xué)有關(guān)算法／程序設(shè)計(jì)來說，已經(jīng)是相當(dāng)了不起的開源軟件了。parallel unified multipole algorithm for Electromagnetics (Puma-EM). Aim is providing surface Method of Moments for Electromagnetics, Enhanced by using the Multilevel Fast Multipole Method. Code is parallelized and runs on Desktops and clusters.

H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were Enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.

Fortran has always been the principal language used in the fields of scientific, numerical, and engineering programming, and a series of revisions to the standard defining successive versions of the language has progressively Enhanced its power and kept it competitive with several generations of rivals. Beginning in 1978, the technical committee responsible for the development of Fortran standards, X3J3 (now called J3), laboured to produce a new, much- needed modern version of the language, Fortran 90. Its purpose is to "promote portability, reliability, maintainability, and efficient execution... on a variety of computing systems". The standard was published in 1991, and work began in 1993 on a minor revision, known informally as Fortran 95. Now this revised

Recently millimeter-wave bands have been postu- lated as a means to accommodate the foreseen extreme bandwidth demands in vehicular communications, which result from the dissemination of sensory data to nearby vehicles for Enhanced environmental awareness and improved safety level. However, the literature is particularly scarce in regards to principled resource allocation schemes that deal with the challenging radio conditions posed by the high mobility of vehicular scenarios
