摘　　要：异构多核DSP是在同构多核DSP中引入了通用处理器核来管理系统,让DSP专注于信号的处理,这种异构模式大大提升了DSP的信号处理性能。为适应嵌入式通用信号处理平台对小体积、低功耗和高性能等方面的要求,讨论了一种基于异构多核DSP的信号处理系统设计,给出了系统的硬件结构设计和高速互连实现方案,详细介绍了Hyperlink和RapidIO等关键高速电路实现方法并对其性能进行了分析。The general purpose processor is introduced in the Isomorphic Multi-core DSP to manage the system and allocate tasks,so that the DSP core could focus on signal processing. Compared with traditional DSP,the heterogeneous multi-core DSP greatly improves the signal processing performance. In order to meet the embedded system' s requirement of small size,low power consumption and high performance,a heterogeneous Multi-core DSP based signal processing system is designed and implemented. The hardware structure design and high speed interconnection scheme of the system are given,the realization of the key circuit such as Hyperlink and Rapid IO were introduced in detail,and the performance were analyzed.
