摘　　要：研究实现了计算高度密集型应用在异构多核DSP上运行的方法.即利用存储在RISC核外设总线上的FLASH中的应用程序,通过异构多核DSP目标板加电,自动加载到RISC核RAM执行,该应用程序将计算高度密集型应用的DSP程序加载到DSPs核上,并利用RISC核向DSPs核点火执行.主要介绍了异构多核DSP中的RISC核和DSP核的复位、启动方法,DSP核的多种冗余降级工作模式,详细分析了RISC核控制DSP核的原理及操作方法.提出的运行方法完整有效,为相关的研究人员打下了良好的基础.The research implemented the method of highly-intensive computing applications running on the Heterogeneous multi-core DSP.Using the applications stored in the FLASH of peripheral bus of RISC core,with the Heterogeneous multi-core DSP target board power-up,automatically loaded into the RAM of RISC core and implement,the application load the Highly-intensive computing applications to the DSPs core and implement the RISC core by using DSPs cores.Introduce the reset and start method of DSP core and RISC core in the Heterogeneous multi-core DSP core,and many redundant and degraded mode of DSP core,we analyzed the principles and operation methods of the RISC core controlling DSP core in detail.This method of the article is complete and effective,and then lay a good basis for the researchers.
