| 摘 要： | 为了实现DSP程序的高速运行,DSP利用自身对FLASH进行烧写,将程序写入FLASH中,在上电时将程序从低速的FLASH加载到高速片中SRAM内,然后在SRAM里高速运行,这个过程称为自举。介绍了TI新一代高性能32位浮点DSP芯片TMS320VC31外扩1片AMD公司的1M~*8位FLASH(AM29LV800)并行自举的具体实现过程,着重讲述了自举系统的硬件设计、DSP对FLASH的烧写程序以及具体的操作步骤。

| Abstract: | In order to run the DSP program rapidly,DS P programs FLASH by itself and loads the program to the high speed SRAM from the low speed FLASH after DSP is electrified.The above-mentioned progress is called DSP's Boot Loader.This paper introduces the detailed process of the parallel-port Boot Loader based on the 1M~*8 bits FLASH(AM29LV800)from AMD of the last generation high performance 32-bit floating-point DSP TMS320VC31 from Texas Instruments.The hardware,software and the detailed process of the Boot Loader... |
