Abstract
PURPOSE: To improve the processing performance of CPU by adding an instruction by which data transfer has ended to the end of the queue of instructions by which the data transfer has ended.
CONSTITUTION: In a data processor equipped with hardware enabling the queue of commands to be used as an interface, data transfer unit 15 has input-output bus 14, main memory 16 is stored with programs and data, and CPU17 reads sequentially programs in memory 16 to execute instructions. Then, unit 15 takes the initial instructions out from queues 33...35 of commands in queue for data transfer to bring the data transfer to effect, and instructions by which this data transfer has ended are added through logic to the ends of queues 31 and 32 of instructions by which the data transfer has ended. Consequently, equipping the data processor with the hardware enabling the queues of commands to be used as an interface results in the improvement of the processing performance of CPU.
