Abstract :
A very small, high quality RELP Vocoder has been implemented with commercially available Integrated Circuits. This full-duplex, single-card design uses two TI TMS320 Digital Signal Processors. One processor implements the RELP Vocoder Analysis algorithm and the second implements the Synthesis algorithm. The Vocoder operates with a software-controlled, flexible data rate between 9.6 and 32 KBPS. It occupies less than 35 square inches with a power consumption of less than 5 W. A real-time demonstration is available.
