摘　　要：介绍了TMS320VC5402外挂程序存储器的在线编程技术,给出创建系统引导表的具体步骤并在此基础上重点讨论了16位并行引导装载方法,并在以DSP为核心的氢钟自动调谐系统中得以仿真实现。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. Technology and methods of online programming for DSP ＋ FLASH are presented here. Then this paper discusses how to make a Boot table and program it to FLASH. 16-bit parallel bootload method is major described in this paper. The method introduced can be simulatedly realized in error signal processing circuit of hydrogen atomic clock CAT system.
