双核嵌入式处理器耦合结构分析

Analyses on the Coupled Structure of Dual-core Embedded Processor

通过比较传统双CPU通信模式,指出共享存储器方法的优越性,分析了两类新型双核嵌入式处理器TMS320DSC系列和TMS320VC547x系列的特点,描述了嵌入式双处理器耦合结构中采用共享存储器交换数据的几种基本通信方式,介绍了嵌入式双处理器并行处理的基本操作方法。

Comparing with all kinds of the traditional communication modes between two CPUs, this paper points out the advantages of shared memory method, analyzes the characteristics of the new type embedded processors both TMS320DSC and TMS320VC547X and also describes the basic communieation methods by using shared memory to swap and store data as well as it introduces the basic parallel processing methods of the embedded processors.
