    Abstract: In a micro-controlled data handling system the number of lines and pins required to transfer control signals from the microprogram controls to be 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.

    Abstract: Arrangement for Error Recovery in a Self-Guarding Data Processing System In self-guarding data processing systems most of the error handling activities have to be implemented without any program support from a dedicated subsystem which is secured against the error problems which it has to handle. The self-guarding data processing system must be reset and restarted to handle the error procedures by itself. This means that the error status manifested in many check latches has to survive the reset and restart activities and that it has to be accessible by instructions within the processor in error. Check indicator latches are provided which are set by the error signals and which are read by the error handling program routines for further evaluation. They can only be reset by the error handling program routines.
