ABSTRACT:
An error recovery system used in a pipeline architecture type computer system for recovering from an error in a control word for an instruction without interrupting the sequence of processing control words by the computer system. The computer system processes instructions in a sequence of overlapping FLOWs where each FLOW is comprised of a sequence of cycles. An instruction control word is processed in each cycle of each FLOW. The error recovery system comprises a first storage for storing, for a given cycle of a FLOW, all the control words for all the instructions, a second storage for storing a control word read from the first storage and an error recovery logic for detecting an error in the control word read from the first storage and stored in the second storage and for correcting the error in the control word in the first and second storage.
