microprocessing unit (mpu) The main constituent of the hardware of the microcomputer. It consists of the microprocessor, the main memory (composed of Read/Write and Read-only memory), the input/output interface devices, and the clock circuit, in addition to buffer, driver circuits, and passive circuit elements.; 微型計算機的主要硬件部分,包括微處理器、主存儲器(由讀寫及只讀存儲器組成)、 輸入輸出接口裝置、時鐘電路以及緩沖器、驅(qū)動電路和無源電路元件。
In this thesis, i argumentate the whole scheme of embedded measurement and control system platform : microsoft windows ce rtos and intel strongarm 1110 microprocesser; the communication ports including 10m ethernet port, 9 pin rs232 port and gpio . lastly, specially analyzing software and hardware design of ethernet port, rs232 port and watchdog module . the measurement and control system based embedded system has been delivered to consumers to use, and due to its high stability and reliability, consumers highly approbate it 文中論證了嵌入式測控系統(tǒng)平臺的整體方案:微處理器采用intel公司32位strongarm1110,實時操作系統(tǒng)(rtos)采用windowsce,通信接口有ethernet網(wǎng)絡(luò)接口、rs232串行通信接口以及通用輸入/輸出(gpio);深入剖析了系統(tǒng)平臺硬件、軟件的體系結(jié)構(gòu)及開發(fā)流程;重點說明了系統(tǒng)平臺的通信模塊??以太網(wǎng)通信端口和串行通信端口以及wdt/lvs(看門狗/低壓檢測)模塊的設(shè)計與實現(xiàn)方法。
