This tutorial will deal with getting input using DIRECT Input. All you will need to
run and/or compile this tutorial is a keybaord, mouse, DIRECTX 8.0 or 9.0 and the
DIRECTX 8.0 or 9.0 SDK.
Patterns of Enterprise Application Architecture is written in DIRECT response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform
DM642上的DMA性能一個簡單的介紹和分析。
DM642中的DMA稱為EDMA（Enhanced DIRECT Memory Access）,其EDMA控制器支持64個相互獨立的DMA通道，每個通道都可以接受系統外設事件的觸發或者CPU的指令的觸發，不同DMA傳輸之間還可以進行連接，構成各種復雜的DMA操作，在600MHz主頻時可以提供2.4GB/秒的數據吞吐量。具備的1維、2維傳輸模式，非常適合圖像的處理。
