A high-speed programmable digital signal processor (DSP) VLSI with an 18-bit floating-point architecture and a 32-bit microinstruction has been fabricated using 1. 2- mu m CMOS technology. The device contains 280K transistors and executes every floating-point operation within a 50-ns machine-cycle. The architecture differs from that of the digital speech signal processor reported previously in its high-speed parallel pipeline structure, 16K-byte on-chip microprogram ROM, floating-point ALU capable of 50-ns operation, and enhanced DSP instruction set.
