摘要
嵌入式Linux数据采集系统平台基于Motorola公司的MPC823e处理芯片,采用Cypress公司的64kbyte双口异步静态RAMCY7C028V,以Linux2.4.4内核作为微型操作系统。文章介绍了如何构造双口异步RAM的硬件接口;并在硬件基础上,详细设计编写了嵌入式Linux下双口异步RAM驱动程序;并编写了相应的测试程序验证了硬件和软件设计的正确性。
The embedded Linux data acquisition system platform is based on Motorola＇s MPC823e CPU. It uses Cypresses 64 kbyte dual port asynchronous static RAM CY7C028V, and makes Linux 2. 4. 4 kernel as its micro operation system. This paper introduces how to build dual port asynchronous RAM hardware interface. On the basis of hardware, the design of dual port asynchronous RAM driver program and the test program based on the driver on embedded Linux are discussed. The correction of the hardware and software design are tested and verified in the end.
