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 revolution of automation on factory floors is a key driver for the seemingly insatiable demand for higher productivity, lower total cost of ownership,and high safety. As a result, industrial applications drive an insatiable demand of higher data bandwidth and higher system-level performance. This white paper describes the trends and challenges seen by designers and how FPGAs enable solutions to meet their stringent design goals.

在實際應用中,編程者往往喜歡程序能自動生成word說明文檔,說明程序運行的狀況或運行的結果;或者程序能提取數據庫的內容生成word表格,使用戶能方便的查看和修改,打印。但是VC++中調用word的確不容易,特別是對word中各種函數的使用,本文以作者的工作經驗詳細介紹一下如何調用word和進行word表格的填寫,有同樣需求的編友也可查看一下MSDN中的automation Microsoft Office 97 and Microsoft office 2000。

操作系統有所耳聞,它是微軟已推出的三種操作系統內核之一,是一種實時操作系統。雖然它是一種實時操作系統,但是從96年發布v1.0到現在,它的主要用途都在民用領域,比如Pocket PC、SmartPhone、automation。不像VxWorks,應用于航空航天、軍事等領域。現在linux、VxWorks廠商也都看好嵌入式民用市場,激烈競爭在所難免。我看好Windows CE,因為微軟在PC領域實在太強,用戶也早已熟悉了微軟的產品,把PC下的技術移植到嵌入式領域,首先在操作界面方面就占了上風。

我們在編寫程序,開發軟件的過程中如果能利用已有的程序的功能,那么可以大大減輕開發過程中程序員的工作量,同時達到事半功倍的效果。例如在工程中,許多軟件需要文字處理功能,雖然MFC提供了一些方法,但是具體實現起來既費事,又有一定的困難,如果我們可以直接使用OFFICE提供的功能,豈不美哉!要實現這一目的,只需要利用微軟的ActiveX automation技術就可以輕松實現。本例主要講述了自動化的概念,并通過一個操作Word文檔的程序來幫助讀者朋友理解Visual C++編程中如何實現自動化。
