Title: Dma controller
Inventor: KONDOU HIROIKU
IPC: G06F13/28
Filed: 1990-03-09
Abstract: PURPOSE:To reduce the circuit scale and to shorten the working time for a decoder of a control circuit by securing the same input to be decoded and its output between the read and write states. CONSTITUTION:A temporary counter 103 outputs the value equal to the count value in a read state and then outputs the inverted value obtained by subtracting the count value from the transfer frequency to the decoder 104 in a write state respectively. Therefore the output of the counter 103 inputted to the decoder 104 always shows the desired number of bytes to be transferred regardless of the read or write state. A selector 105 inputs a read operation defining part (source field) and a write action defining part (destination field) of an action defining register 102 to the decoder 104 with switch carried out between both defining parts according to each state. As a result, the same input to be decoded and its same output are secured between the read and write states. Thus the number of signal patterns to be decoded is halved. Then the circuit scale is reduced and the working time is shortened for the decoder 14.
