Abstract
In a signal processing apparatus which stores a program inside, and performs a series of processes on a received signal according to the program, such as an arithmetic operation or a delay process, and outputs the processed signal, for rewriting the program in order to change the contents of the processing. Program data is prevented from being output in synchronism with a sampling clock generated at the timing of an input signal. This design can minimize noise occurring due to a change in the algorithm of the signal processing during signal processing. Further, in the case where a program for a separate signal processing circuit is rewritten in response to an instruction that is given from outside at an arbitrary timing, noise can also be minimized by proceeding with the rewriting in synchronism with a sampling clock.
