Abstract: A PROGRAMMABLE digital signal processor IC offering speed, precision, and flexibility for a variety of telecommunications applications will be discussed. Functionally, it is a specialpurpose microcomputer whose instruction set and arithmetic and addressing capabilities are optimized for realtime signal processing functions including filtering, detection and modulation. The processor can decode an instruction, fetch data and perform a 16b by 20b multiplication and a full 36b product accumulation in one machine…
