Abstract
PURPOSE: To perform the data transfer between memory areas and to increase the processing efficiency, by reading out the command word from the list address given for the 1st memory area data transfer command word list address and the 2nd memory area data transfer command word.
CONSTITUTION: Before the start of data transfer, to the register 120, the 1st memory area data transfer command word list address is set and to the register 140, the 2nd memory area data transfer start address and transfer command word such as transfer word are set respectively. The 1st memory area data transfer command word is read in the register 130 from the list address by the transfer start trigger, and the data 210 is transferred through the reception circuit 110, buffer 150 and transmission circuit 180 with the information. The renewal circuit 170 renews the registers for transfer control.
