【摘要】 在基于DSP的系统设计中,为了保证掉电时程序不丢失,总是将程序保存在非易失性的存储器中,系统在上电复位时便可将其引导到DSP内部的RAM来执行。文中以 FLASH作为引导存储器,描述了引导引脚以及相关寄存器的设置,分析了采用EDMA传输方式将代码从FLASH复制到DSP的过程,并对引导程序给出汇编语言的代码实现。更多还原

【Abstract】 Based on the device about DSP,the program is always preserved in Nonvolatile memory to avoid the program lost once power is off,when system is resetted,the program is bootloaded to RAM of DSP.The FLASH is regarded as booting memory which describes the configurations of the booting pins and registers and it analyzes the process that how to copy the program codes to DSP by means of EDMA and realizes the program codes by using Assembly Language.更多还原
