Abstract
PURPOSE:To increase processing speed by sending a timing signal only without sending a fetching address when an address number is continuous. CONSTITUTION:When it is detected that the address number of an instruction word in a memory block 17 to execute the fetching request after this is not continuous to a preceding address number, a fetching address is sent from a fetching address preparing circuit 10A and held at an address latch 14. When it is detected that the number is continuous, a timing signal is sent from a timing signal generating circuit 10B, and an address counter 19 proceeds the fetching address at the time of completing respective fetchings every time the timing signal occurs based on the fetching address.
