Variable function information processor

摘要

There can be provided a variable function information processor in which a logic module (10) with the further decreased number of transistors used in the logic module constituting the variable function information processor is provided, a function of being able to realize both a combinational logic circuit for-performing a full addition operation of input signals in accordance with a control signal and outputting the sum and a sequential circuit for temporarily holding the input signal to delay the signal and outputting it by the same logic module is provided, and in a semiconductor circuit element group for constituting the combinational logic circuit and the sequential circuit, a common part of the combinational logic circuit and the sequential circuit is used for both the circuits, whereby the number of elements can be further decreased, and the resources of the variable function information processor can be effectively exploited.
