Speech communication hardware

This paper describes a fast digital signal processor working on 16 bits data words. Unlike the other systems this processor don´t use bit slice components keeping high performance (5 Million instructions per second) and programmation simplicity with a microprocessor-like instruction set. This processor is generally connected to a general computer but its input-output system simplifies real time applications. Experimental results with a formant synthesizer and a linear prediction vocoder are demonstrated.
