PURPOSE:To reduce the processing time and to realize the effective use of a processor, by connecting the processor to an asynchronous memory continuous region shift device. CONSTITUTION:The control parts 3 and 1 of a memory continuous region shift device 3 work in response to a continuous region shift command given from a processor 1. Thus the read-out of contents of a shift originator region 5 of a memory 2 is controlled together with the writing to a shift destination region 6, the zero writing to the region 5, etc. These controls are carried out asynchronously with the processor 1 until the count value of a shift remaining cell number holding register 3.4 is set at zero while referring to the contents of a shift originator address holding register 3.2, a shift destination address holding register 3.3, a shift residual number holding register 3.4 and a zero clear need/ no-need information holding register 3.5 of the area 5, in the device 3 to which the control information 4 is set for the device 3 of the memory 2. This independent processing reduces the processing time and ensures the effective use of the processor with a load reduction. |
