Abstract
PURPOSE: To enhance the effeciency of the informaion processing system by using a dedicated processing module in case of data transfer of memory contents to reduce the load of CPU.
CONSTITUTION: In the information processing system where memory 3 and I/0 devices are connected to CPU 1 through bus line 2, memory data moving controller 4 is connected. In this controller 4, data register 5 which stores data read from memory 3 and data written to memory 3, address registers 6 and 7 which are equipped with the count facilities to store addresses, and length register 8 which is equipped with the count facilities to store the move quantity of memory 3 are provided. Further, bus interface 9 which is located between bus line 2 and these registers 5 to 8 and controls the count facilities, which registers 5 to 8 have, and repeats the move operation until contents of the counter reach zero is also provided, thus performing the information processing by analyzing the move instruction issued from CPU 1.
