摘要
TI公司的54xDSP支持各种自举方式,其中,HPI启动方式具有独特的优点。利用单片机完成HPI的自举,可以保留DSP的数据空间,从而提高DSP性能。针对程序代码长度超过片内程序空间的特殊情况,介绍了HPI自举实现方法。
HPI bootloader has special advantages compared to other bootlaoder methods that can be used by TI＇s 54xDSP. For the data memory is reserved through HIP bootloader by MCU, the performance is improved heavily. At the same time, the solution of bootloader by HPI is presented for the special condition when the length of programmer code is larger than that of the program space on chip.
