The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the right package has becomeone of the key considerations for the systemdesigner.

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.

The purpose of this computer program is to allow the user to construct, train and test differenttypes of artificial neural networks. By implementing the concepts of templates, inheritance andderived classes from C++ object oriented programming, the necessity for declaring multiple largestructures and duplicate attributes is reduced. Utilizing dynamic binding and memory allocationafforded by C++, the user can choose to develop four separate types of neural networks:

Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP connection pool. One could easily implement a IMAP connection pool, then take the existing code and implement a LDAP connection pool. The program grows, and now there is a need for a pool of threads. So just take the IMAP connection pool and convert that to a pool of threads (Copy, paste, find, replace????). Need to make some changes to the pool implementation? Not a very easy task, since the code has been duplicated in many places. Re-inventing source code is not an intelligent approach in an object oriented environment which encourages re-usability. It seems to make more sense to implement a pool that can contain any arbitrary type rather than duplicating code. How does one do that? The answer is to use type parameterization, more commonly referred to as templates.

本書第二版和第三版之間的變化非常大其中最值得注意的是C++已經通過了國際標 準化這不但為語言增加了新的特性比如異常處理運行時刻類型識別RTTI 名字空 間內置布爾數據類型新的強制轉換方式而且還大量修改并擴展了現有的特性比如模 板template 支持面向對象object-oriented 和基于對象object-based 程序設計所需 要的類class 機制嵌套類型以及重載函數的解析機制也許更重要的是一個覆蓋面非 常廣闊的庫現在成了標準C++的一部分其中包括以前稱為STL 標準模板庫的內容新 的string 類型一組順序和關聯容器類型比如vector list map 和set 以及在這些類型 上進行操作的一組可擴展的泛型算法generic algorithm 都是這個新標準庫的特性本書 不但包括了許多新的資料而且還闡述了怎樣在C++中進行程序設計的新的思考方法簡而 言之實際上不但C++已經被重新創造本書第三版也是如此

The Art of C++ by Herbert Schildt ISBN:0072255129 McGraw-Hill/Osborne © 2004 The author of this text applies C++ to a wide variety of high-powered, practical applications, each focusing on a different aspect of the language. Examples range from a garbage collector subsystem and a thread control panel to AI-based searches and more.
