Abstract
PURPOSE:To reduce the amount of hardware to simplify the control by dividing data from a storage device to partial data and distributing these partial data to desired storage parts in 1:1 to store them in designated storage positions. CONSTITUTION:An address circuit 7 sends address information indicating an address (n) to an address operating circuit 8 and a local memory part 6. The circuit 8 sends this information to a local memory part 5 as it is. Next, word data in an address N of a system memory 1 is transferred to a data handling circuit 4 by the control of a direct memory access DMA control circuit. The circuit 4 stores high-order byte data and low-order byte data of data in the address (n) of memory parts 5 and 6. Hereafter, word data in an address N+1 and following addresses of the memory 1 are stored in an address n+1 and following address of a memory 12 similarly. Thus, the amount of hardware is reduced to simplify the control.
