Digital Signal Processing Systems

摘要

A signal processing system may include a multiply-accumulate (MAC) unit to generate output data by performing multiply-accumulate operations on first and second input data in response to a stream of MAC instruction words, where the MAC unit is pipelined to enable it to perform a multiply-accumulate operation in response to each MAC instruction word. The system may also include an instruction generator to generate the stream of MAC instruction words by performing loop expansion on a stream of intermediate instruction words, where one intermediate instruction word may comprise a group of fields to set up the MAC unit to execute in response to the one intermediate instruction word.
