ABSTRACT:
The present invention features performance of operation processing between a signal obtained by converting a coefficient into a Booth code with a Booth encoder, storing the Booth code in a memory device in advance and reading out the stored Booth code for processing an input signal in a semiconductor operation device or a digital filter. As a result, a coding operation by a Booth encoder of the present invention will be performed only once at the time of rewriting a coefficient and will not be repeated, thereby enabling a high-speed operation and realizing reduction of circuit scale at the same time by using an encoded Booth code directly in an operation after a coefficient has been determined.
