Abstract
PURPOSE: To make easy the high speed of processing, by using DMA function.
CONSTITUTION: When start signal is outputted from CPU 5 to the control circuit with the input and output instruction and data request is made from the bus interface 7 to the channel 6, the channel 6 requests data transfer with DMA and feeds the data required by the special operation circuit 8 via the bus interface 7. The special operation circuit 8 perform bit operation and it is written in memory with DMA system via channel, and when the transfer of the result of operation is finished, the end of operation is informed to CPU 5 and all the process of operation is finished.
