Study on the 8-Bit Parallel Boot Mode for TMS320VC5402

In the digital signal processing system based on DSP,the program is always preserved in nonvolatile external memory to avoid the program lost once power is off,when the system is resetted,the program is bootloaded to RAM of DSP.The 8-bit parallel bootload process for TMS320VC5402 is introduced in the article.At the same time,the hardware design is illuminated.Finally,the steps of building the boot table are given.
