摘要
多处理器硬件平台模式在工业控制系统中应用广泛。而MCU+DSP的双处理器模式设计较为突出,利用DSP完成数字信号处理功能,MCU实现管理、通信、人机接口等异步系统控制功能。各处理器在功能上相互分工并通过数据传输完成预期任务,提高系统性能。给出了基于MCU+DSP嵌入式平台的主机接口与引导设计方案。
In the design of industrial control system ,the multiple processor hardware platform is used widely.The dual processors platform of MCU ＋DSP is the best.DSP can process digital signal and MCU can realize functions of the asynchronous system such as system management,communication and MMI （man-machine interface）. Each processor works separately and communicates data to accomplish one target task.This paper presents a design of host interface and boot of embedded hardware platform based on MCU＋DSP.
