ABSTRACT:
A signal processing apparatus executes a plurality of microprograms stored in a microprogram memory device in a time-sharing manner, so as to perform arithmetic operations on a digital signal entered by a signal input device. A delay memory device that delays the digital signal. The delay memory device has a plurality of delay areas that are independently provided for the respective microprograms, such that each of the microprograms that is being executed uses a corresponding one of the plurality of delay areas so as to delay the digital signal, and a common area that can be accessed by all of the microprograms. As a result, data such as tables for use in common by the plurality of microprograms can be stored, and the stored data can be easily used by each microprogram, without making the system complicated or increasing the cost of the apparatus.
