Abstract :
The modular voice processor (MVP) is a single DSP (digital signal processing) chip implementation of a multifunction vocoder in a small, low-power module. With the capability of processing FED-STD-1015 2400 bit/s LPC (linear prediction coding) and FED-STD-1016 4800 bit/s CELP, the MVP module has potential applications for numerous DOD and Federal Government applications. Attention is given to such MVP features as hardware, interfaces, bitstream, and software architecture
