摘　　要：分析了TM S320VC 5509的串行数据传输(Seria l Periphera l In terface,SP I)引导装载过程,设计出特别适用于对系统体积有严格限制的的简单电路,以及引导方式易于控制的能够满足普通应用的软件程序,最终完成自举启动功能,其数据传输率为3 M Bps.此法对后期硬件扩展与软件升级都有很大帮助.The serial peripheral interface （SPI） bootload of TMS320VC5509 is analyzed in details. Simple circuits for the limited system volume is designed especially and the software program with the easily controlled Bootload is designed and the common application can be fulfilled. The Bootload is achieved finally. Its data transmission speed is 3 MBps. This method is very helpful for the software upgrade and hardware development of the later stage.
