Abstract
1,243,872. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 2 Jan., 1969 [15 Jan.. 1968], No. 257/69. Heading G4A. In a data processing system, detection of error during the performance of a function on data causes retry using the original data saved in a selected one of a plurality of saving means. In a microprogramme-controlled stored-programme computer with main and local core stores and a read-only microprogramme store, each instruction requires one or more sets of microinstructions, each set being of type » load,» » wait,» » status fetch » or » normal «. Detection of an error causes retry of the current set using saved information in accordance with the type as indicated by bi-stables set by decoded microinstruction fields during normal sequencing. These fields also control the saving. The corresponding fields are decoded in a different way during retry because of the influence of a retry latch on the decoder. The retry latch is set by the error detector and may be set by the decoder. Retry is controlled by micro-instructions starting at read-only store address zero. The decoder outputs are delayed to allow time for detection of any error. Another decoder is provided for the rest of the microinstruction. Back-up registers &c. are provided for saving: instruction address, data from main and local store, local store address and status bits. Saved data is used for replacement on retry only if necessary, triggers being provided to indicate if data was being regenerated back into or being modified in the main or local store when the error occurred. Repetitive retries are possible, up to a maximum number. Retry is prevented if the maximum has been reached or if a » machine check interrupt» trigger is set, the latter interrupt occurring and the operator being notified in either case. Error detecting and correcting facilities may be provided for the main and local stores, including means for generating check information and storing it in a core store associated with the main or local store as the case may be when storing data, and accessing it and using it for error detection and correction when reading data out. The computer could alternatively use conventional instruction decoding rather than a microprogramming read-only store. Reference is made to Specification 1,243,871.
