ABSTRACT:
A register circuit capable of use in various components of a computer. The register circuit includes two registers and logic circuitry that enables plural data buses to be selectively connected in various configurations to the data inputs and outputs of the registers. In an embodiment showing the register circuit constructed using emitter coupled logic, a clocking circuit generates clocking signals for selecting the data buses to be connected to the input of each register. Each register comprises plural master-slave flip-flops which receive the clocking signals from the clocking circuit and operatively connect the flip-flops to the selected bus or buses in response to such signals.
