Abstract

PURPOSE: To supply a logical operation controller which performs the logical operation between inputted n-bit data and n-bit data which has been stored already, by using n-number arithmetic control units for one bit to input n-bit data.
CONSTITUTION: Plural sets of program codes where an operation code, an I/O command and a data memory address are made into a set are stored in program memory 4. Logical operation units 1, 2 and 3 are the same unit and operate synchronously with the same clock signal and read simultaneously operation codes stored in program memory 4 and have respective operations designated. At this time, bits of the I/O command and distributed to input interface 8, output interface 9, data memory 6 and register memory 7 one by one, and the unit which bit "1" is given to is operated.
