The Boot Process About FLASH Based on the SoC System That Embedded Multi-DSP

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.
