An LSI digital signal processor

This paper describes a recently developed single-chip digital signal processor designed to satisfy the requirements of a wide range of telecommunication applications. The device is fabricated with N-channel MOS technology and contains 65,000 transistors within a 7.9 by 7.44 mm area. It has many features for efficient pipelined operations and achieves a high degree of throughput. The processor also has large data memories: 512 words of ROM and 256 words of RAM. The I/O unit includes an on-chip DMA controller which allows the processor to be readily interfaced with other devices. Multiprocessor systems are constructed with no external logic.
