Abstract
PURPOSE: To increase the throughput with a simple constitution, by installing the address incrementer which converts the storage contents of the address register into the subsequent address designation signal in response to the address designation output of the register.
CONSTITUTION: A successive and parallel process is carried out for four types of programs, the corresponding program address registers 11W14 are provided in order to read an instruction of the program in correspondence to each of the registers 11W14. The selection for these registers is carried out by means of the contents of the counter 15 provided separately. According to the count contents, the selection signal to select one of the address registers is decoded 16. Then the address incrementer 18 is provided to convert the memory contents of the address register into the subsequent address designation signal in response to the address designation signal output of the register. As a result, the throughput can be increased with a simple constitution.
