    Abstract: ARRANGEMENT FOR MICRO INSTRUCTION CONTROL In a micro-controlled data handling system the number of lines and pins required to transfer control signals from the microprogram controls to integrated circuit modules controlled by such signals is conserved by using two bussing paths for distributing the control signals to the modules. A first path is dedicated exclusively to pre-decoded control signal functions and a second path is shared for transferring both data and control signal functions. Each controlled module contains an additional decoding circuit for combinationally decoding control signal functions received through both paths.
