Abstract
A register read control method for use with an information processing apparatus for executing a plurality of instructions in parallel during pipeline processing. The apparatus includes a register file, a register designation selector, a cache register, a selector, an arithmetic circuit, a register cache pass and a comparator. When the comparator detects a coincidence between the data in the cache register for the current instruction and the operand in the next instruction, the comparator causes the selector to select the register cache pass as input thereto and to move the contents of the cache register back directly to the cache register via the register cache pass.
