<p>PURPOSE:To perform a signal processing having generality, by inputting a synchronizing signal to a control signal generating circuit to generate control signals required for a data input circuit, coefficient input circuit, etc., and by delaying an input synchronizing signal in accordance with each function. CONSTITUTION:One function out of eight functions is selected by combinations of signals ''0'' and ''1'' input to input terminals F0, F1 and F2 and is input to select signal generating circuit 500 to generate select signals f0-f11. These signals are input to data input circuit 100, coefficient input circuit 200, and adding circuit 400 and become select signals for respective selecting circuits. The synchronizing signal input to input terminal Sin is input to control signal generating circuit 600 to generate various control signals required for respective parts of circuit 100, circuit 200, multiplying, circuit 300, and circuit 400, and the input synchronizing signal is delayed in accordance with each function and is output to terminal Sout.</p> |
