    Patent number: 4745605
    Abstract: In a data processing machine that generates a control word and that includes a plurality of registers connected to receive respective copies of the control word for execution in sections of the data processing machine, the present invention provides an apparatus for detecting an error condition in the execution of the control word. The apparatus detects an error in any of the respective copies of the control word. Further, a second means, responsive to the one copy of the control word in one register, is included for analyzing the one copy to identify a class of possible errors.
