摘　　要：介绍了一种内含多个DSP的SoC系统,并对SoC中的FLASH引导过程进行分析;由于大规模SoC系统中内部嵌入多个DSP以及SoC系统本身内部存储程序的空间有限,且每次上电后用户加载的程序会丢失,需要每次重新加载烧写.而借助于SoC系统中的多个DSP核的引导功能,通过EMIF接口每次自动加载外接于SoC系统的FLASH存储器里的程序,实现上电后SoC系统自动运行用户程序.介绍了该多核SoC系统的相关boot功能的软硬件配置设计及引导控制程序,并对引导过程进行分析以及对多DSP核SoC系统的boot功能进行了仿真验证及测试.结果表明该多核SoC系统能够快速、准确地对FLASH程序进行引导和搬移;是一种有效的和可行的多核SoC系统引导方法.The paper proposed one SoC system that embedded multi-DSP,and discusses the boot process about the FLASH connect at the SOC system.Thanks to the space in the SOC system that use to storage the code is limited, and the code that users need load will lost at that the SoC system power on every time.So users need write the code again. The SoC that multi-DSP embedded in can run the users'code automatically in virtue of the boot function of the DSP in SoC that get across the EMIF interface.And it introduces the hardware and software design about the boot process of the SoC system,simulate and test the boot function about the SoC chip.The result indicated that the multi-DSP core in SoC can boot and move the code in the FLASH connect at the SoC system to the inner RAM of the SoC system fast and exactly.It is an effect and viable boot method that can apply in SoC embedded multi-core.
