針對主控制板上存儲器(SRAM) 存儲的數據量小和最高頻率低的情況,提出了基于SDR Sdram(同步動態RAM) 作為主存儲器的LED 顯示系統的研究。在實驗中,使用了現場可編程門陣列( FPGA) 來實現各模塊的邏輯功能。最終實現了對L ED 顯示屏的控制,并且一塊主控制板最大限度的控制了256 ×128 個像素點,基于相同條件,比靜態內存控制的面積大了一倍,驗證了動態內存核[7 ]的實用性。

Advanced UNIX Programming is the long-awaited (19 years!) update to the 1985 original. Maybe "update" isn t the right word--of the 750-or-so pages in the new book, there are maybe two dozen paragraphs that are unchanged. The original covered about 70 system calls, and the new one covers about 300. (這是Advanced UNIX Programming的附書源碼)

非常好的優化算法的書,詳細介紹了蟻群算法和粒子群算法以及相關的matlab工具箱,講了理論和應用給出了工具箱的下載地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a position and a velocity. These particles wander around the hyperspace and remember the best position that they have discovered. They communicate good positions to each other and adjust their own position and velocity based on these good positions.

This application report presents basic code for initializing and operating the TMS320LF240x DSP devices. Two functionally equivalent example progra ms are presented: one written in assembly language and the other in C language. Detailed discussions of each program are provided that explain numerous compiler and assembler directives, code requirements, and hardware-related requirements. The programs are ready to run on either the TMS320LF2407 Evaluation Module (EVM) or the eZdsp LF2407 development kit. However, they are also intended for use as a code template for any TMS320LF240x (LF240x) or TMS320LF240xA (LF240xA) DSP target system.

The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC938 in order to reduce component count, board space, and system cost.

an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.
