Abstract

PURPOSE: To quickly perform the processing by masking lower n-number of bits of tagged data, which designates the address of a storage means, based on the tag mask signal outputted from a control signal.
CONSTITUTION: A microprogram controller 7 discriminates whether contents of the register of a register file 10 designated by a register designating field should be handled as tagged data or not by the classification of the operation code. If the controller discriminated that said contents are handled as tagged data, a tag mask circuit 8 masks lower two bits of the address given to a memory address register 5 on the basis of a tag mask signal TM outputted from the controller 7. Thus, a main memory 1 is accessed to perform quick processing.
