Abstract
PURPOSE: To reduce the cost and to make high efficiency, by setting the store comparison FF circuit through the logic address and instruction pre-fetch address for comparison and setting the match FF circuit through the comparison of the logic address and the stop address.
CONSTITUTION: The scratch pad memory 17 incorporates registers including the instruction pre-fetch address 00, stop address 02, and memory error information 04, 05. At memory cycle, the stop address is read out in time sharing with the control circuit 18, it is compared with the logic address at the address comparator 14, and the match FF13 is set when the in agreement. Further, at the storage comparison, the instruction pre-fetch address 00 in the scratch pad memory 17 is read out with the control circuit 18, it is compared with the logic address at the address comparator and the storage comparison FF12 is set when in agreement, allowing the circuit to be only with one address comparator 14 and one scratch pad memory 17.
