Abstract
PURPOSE: To reduce the hardware quantity with holding of the process function by obtaining easily the execution address of the order through the operation and with installation of the correction circuit to the pre-fetch memory access counter, the order register pointer and others each.
CONSTITUTION: Order buffer 102 gives the pre-fetch memorization to several orders to be executed. And the reading position of buffer 102 is designated by order register pointer 103, and at the same time the pre-fetch position of the order is shown by pre-fetch control counter 101. Thus the order execution address can be obtained easily by the operation based on the contents of both counter 101 and pointer 103 plus installation of correction circuit 104. As a result, the hardeare quantity can be reduced with holding of the process function.
