Abstract

PURPOSE: To substitute value for same variables stored in a register file at a high speed by using a double reading port associative register file which performs data writing actions in a single operation to all registers which hold the same value as that of the read data.
CONSTITUTION: A double reading port associative register file 110 stores a register holding the data of the same value as that of the read data and can write data to all registers having the same value in a single operation in a data reading state. Then a tag check circuit 120 checks the tag parts of two pieces of data read out of an optional argument register and work register and decides a process to be carried out based on the checking result. Thus the value can be substituted for the same variables stored in a register file at a high speed.
