摘要
浮点DSP一般运用于对各种数据运算和处理,82C55是一种通用的并行I/O接口芯片,主要为Intel系列微处理器提供外围电路的接口配置。为了解决快速的浮点DSP与相对慢速的输入输出接口芯片82C55间的连接和控制问题,通过对浮点DSP芯片TMS320C32和82C55芯片的读/写时序图的分析,得出两者硬件连接的解决方案,从而实现了用浮点DSP除了完成数据处理功能之外,还能通过可编程接口芯片82C55对外围设备进行控制操作。
The floating DSP is commonly used to process the data and information,while 82C55 is a general purpose programmable I/O device which was designed for use with all Intel and most other microprocessors.It was intend to find a connection solution between fast DSP and 82C55 which was much slower comparatively.By analyzing read/write sequence charts of TMS320C32 and 82C55,find the solution.Besides calculator,can treat floating DSP as controller with 82C55.
