The digital signal processing library (DSPLIB) is a set of C-callable, assembly-optimized functions commonly used in signal processing applications. While TMS320C64x supports both little- and big-endian modes for better system integration, the DSPLIB has been provided in little-endian mode only. Therefore, there has been a strong request for big-endian support from users who need to use big-endian mode for their system development. To fulfill this urgent request, the DSPLIB functions have been converted from little endian to big endian in either linear assembly or hand assembly. This application note presents the usage of the big-endian DSPLIB for TMS320C64x.……
