Central processing unit

Abstract

PURPOSE: To improve the processing ability of the central processing unit as much as possible. CONSTITUTION: Input data dI consisting of the specific number of bits is received and a bit which contains a predetermined logic value (logic (1), e.g.) and meets predetermined conditions (rightmost bit as least significant bit or leftmost bit as most significant bit) is detected in the input data. The central processing unit is provided with a corresponding bit position output means 100 which outputs the bit position (n) of the corresponding bit and a corresponding bit logical value varying means 200 which receives the bit position outputted by the corresponding bit position output means 100 and outputs output data d o varied in the logical value of only the bit specified by the bit position of the input data.
