Abstract

PURPOSE: To maximize the processing efficiency of the whole of the system by providing a means which controls data transfer between a host computer and an anxiliary data processing unit, a means which controls the execution of the data processing, and a state display register.
CONSTITUTION: When CPU 11 sends initial information to command transfer controller CTC25 through bus 14, CTC25 accepts a transfer command from main memory 12 and sets this command in a register of transfer controller DTC23. Direct memory access control part 26 transfers data required for operation from main memory 12 to memory 21 of an auxiliary data processing unit by the signal from DTC23. CTC25 accepts an execution command from memory 12 and sets this command in a register of ececution controller EC24 and executes operation in operation part 22 by the signal of EC24 and stores the operation result in memory 21 and transfers the operation result from memory 21 to memory 12 by the signal of control part 26. When it takes a long time for transfer, the execution time is included in transfer; and when it takes a long time for execution, the transfer time is included in execution, thereby maximizing processing efficiency.
