A programmable digital signal processor integrated circuit has been designed as a general-purpose building block for a variety of telecommunication applications. The device, known as digital signal processor, is a single-chip integrated circuit fabricated in depletion-load NMOS technology and packaged in a 40-pin DIP. This paper describes the silicon very-large-scale-integration (VLSI) implementation of the digital signal processor with emphasis on the circuit design phase. The specific areas discussed are choice of fabrication technology, layout styles, circuit design procedures, and circuit considerations.
