基于SPI接口的MCU加载DSP程序的设计
Bootloading DSP’s Program from MCU Based on SPI
在由MCU和DSP组成系统硬件平台的情况下，为了充分利用系统资源并降低硬件电路尺寸，提出一种利用MCU加载DSP程序的方法。以C8051F340单片机为例，将该单片机的片内FLASH等效成DSP的一个片外程序存储器；并利用SPI协议，通过工作在时钟停止模式的McBSP接口加载DSP应用程序；极大提高了系统资源利用率，并优化了系统硬件布局。
In one system Where hardware platform is composed by MCU and DSP,in order to take full advantage of system resources and reduce the size of hardware circuit,this paper presents a solution of bootloading DSP’s program from MCU.Taking C8051F340 for example,this paper makes an imitation of FLASH of MCU as DSP’s external memory.At last,by means of SPI protocol,bootloading DSP’s program through McBSP interface,which is configured in clock stop mode.This design greatly raises the utilization rate of system resources and optimizes the layout of system hardware.
