| Abstract: | 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. |
