Abstract
A microprogrammed controller for interconnection between a central processor unit and at least one peripheral unit for controlling the transfer of data therebetween in response to instructions from the central processor unit provides for simplified bit manipulation through a feedback circuit which feeds the data to be supplied to the peripheral unit back to the input bus of the controller for further processing. In this way bit manipulation can be accomplished with a single microinstruction to provide for higher speed and efficiency of operation.
