<p>PURPOSE:To make transfer processing efficient by selecting and transferring a register with rewriting executed among a register group within the first processor with a flag when the contents of the register group within the first processor is transferred to the register group of the second processor. CONSTITUTION:A register contents changing flag 208 of corresponding plural bits to correspond to every the one register at least of a register group 206 within a first processor 102 is possessed and a flag giving means 29 to set the corresponding bit of it when the rewriting is executed to the register is provided. Then, when an instruction executing part 21 of the first processor 102 transfers the contents of the register group 206 to a register group 306 of a second processor 104, it selects the set bit within the register contents changing flag 208 and transfers the contents of every the register to correspond to the bit tot he second processor 104. Thus, the number of times of transferring does not depend on the number of times of rewriting and is reduced and transfer processing can be made efficient.</p> |
