Abstract
In a digital signal processor having an improved arithmetic processing efficiency, there is provided in parallel a first ROM for storing branch commands and a second ROM for storing arithmetic commands. The ROMs are connected to a branch command decoder and an arithmetic command decoder, respectively. Operations of a first memory control circuit and a second memory control circuit are controlled in response to instructions from the branch command decoder, while operations of an arithmetic circuit are controlled in response to instructions from the arithmetic command decoder. By processing the branch commands and the arithmetic commands in parallel, the operation efficiency of the arithmetic circuit is enhanced.
