Short Content:     Along with information technology's swift development, digital signal processor (DSP) obtained the widespread application. Nowadays high speed DSP memory no longer based on the Flash structure, but uses the access speed quicker RAM structure. After DSP power failure, in its internal RAM procedure and the data will lose completely, therefore in is separated from simulator's environment, usually the procedure is may carry out beforehand the procedure the code to store outside the piece in EPROM or Flash. On after ...
