ERROR DETECTION AND FAULT SEPARATING MECHANISM

摘要

PURPOSE: To efficiently execute error detection and fault separation by a single error control mechanism. CONSTITUTION: Generally, the error detection and fault separation mechanism requires individual capture latches for capturing respective errors (e.g. from a parity inspector or a time-out counter) in each occurrence of an error and a related mask latch for temporarily or permanently blocking the detection of succeeding errors. The invension is characterized by substituting a single error control mechanism 160 capable of setting up and resetting the error capture latches for the mask latch. A detected error is stored in each capture latch and the capture of succeeding errors is prevented until the mechanism 160 resets the latch.
