Abstract

PURPOSE: To enhance the process capacity for the pre-fetch order control with a simple constitution by providing the order address register, the address holding register and the comparator circuit each and then detecting the coincidence between the order address and the store address.
CONSTITUTION: The m-units (m = 4 in this instance) of order which are read out based on the contents of order address register 6-0 and 6-1 is stored into pre-fetch order buffer 1. The calculation is given to the operand address in which the contents sent from input register 3 is supplied to adder 4, and the address advances between address holding registers 5-1W5-3 corresponding to the process stages of the order. In case the order is the store order, a comparison is given between the calculated store address and the contents of register 6-0 and 6-1 at comparator 9-1 and 9-2, and at the same time the store address of the m - 1st holding register 5-3 is compared with the contents of register 6-1 and 6-2 at comparator 10-1 and 10-2. And when a coincidence is obtained, the rereading is carried out for the order. As a result, the return to the original state is not required in case an overlap is detected, thus enchancing the process capacity.
