Described is a digital signal processor including at least two memories, that is, a microprogram memory for storing a series of microinstructions for instructing a digital signal processing procedure, and a coefficient memory for storing coefficient data required for performing a series of arithmetic operations on the digital signal data. These data being transferred and written into said microprogram memory and said coefficient memory from a host computer system. The coefficient memory has at least two pages corresponding to the total memory area which may be addressed during digital signal processing to be effected by said microinstructions. Page selection of the coefficient memory may be performed from said host computer system. |
