The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.

平凡的單片機,MCS-51單片機教程 1、何謂單片機 一臺能夠工作的計算機要有這樣幾個部份構成:CPU(進行運算、控制)、RAM(數據存儲)、ROM(程序存儲)、輸入/輸出設備(例如:串行口、并行輸出口等)。在個人計算機上這些部份被分成若干塊芯片,安裝一個稱之為主板的印刷線路板上。而在單片機中,這些部份,全部被做到一塊集成電路芯片中了,所以就稱為單片(單芯片)機,而且有一些單片機中除了上述部份外,還集成了其它部份如A/D,D/A等。

在學習VxWorks I/O 系統功能的基礎上,了解的基本I/O、緩沖I/O 及格式化I/O、文件描述符、標準輸入/輸出/錯誤設備的使用。對VxWorks I/O 系統中常用的API 有較為深入的理解。實踐者對I/O 系統的理解和使用的熟練程度將影響后續實踐環節進行順利與否。通過I/O 系統API 與應用程序交互,能方便地對所調試的系統進行監控,是實時嵌入環境軟硬件開發的主要手段之一。實現終端顯示的秒表。精確到1/10 秒。可鍵盤控制暫停/繼續計時/復位功能。
