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加载到高速片内SRAM里,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TMS320VC33外扩一片富士通公司的512 k×16位FLASH(MBM29DL800TA)并行自举的具体实现过程,着重阐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。
In order to run the DSP program high speed rapidly,DSP 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 l.oader. This paper introduces the detailed process of the parallel -port Boot Loader based on the 512K ＊ 16 bits FLASH （MBM29DL800TA） from Fujitsu of the last generation high performance 32 - bit floating- point DSP TMS320VC33 from Texas Instruments. The hardware, software and the detailed process of the Boot Loader is discussed emphatically.
