The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。 Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.

This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.

每個C++/C程序通常分為兩個文件。一個文件用于保存程序的聲明(declaration),稱為頭文件。另一個文件用于保存程序的實現(implementation),稱為定義(definition)文件。 C++/C程序的頭文件以“.h”為后綴,C程序的定義文件以“.c”為后綴,C++程序的定義文件通常以“.cpp”為后綴(也有一些系統以“.cc”或“.cxx”為后綴)

This scheme is initiated by Ziv and Lempel [1]. A slightly modified version is described by Storer and Szymanski [2]. An implementation using a binary tree is proposed by Bell [3]. The algorithm is quite simple: Keep a ring buffer, which initially contains "space" characters only. Read several letters from the file to the buffer. Then search the buffer for the longest string that matches the letters just read, and send its length and position in the buffer.

UML(統一建模語言)是一個繪制軟件概念圖的圖形化記法(notation)。人們可以用它繪制圖形,用這些圖形來表示一個計劃進行的軟件設計的問題域,或者用這些圖來表示一個已經完成的軟件實現。Fowler(譯者注:著名IT 技術作家)描述它們時分成了三種不同的層次:概念層(Conceptual)、規格說明層(Specification)和實現層(implementation),我們將細述后面兩種。
