Abstract

Pass/fail testing of devices for handling substantial output data streams is performed by generating and storing CRC (cyclic redundancy check) information or characters on the first execution of a test and comparing the stored CRC against the CRCs generated by the device under test on subsequent executions of the same test. The process avoids the requirement of large amounts of output data storage for pass/fail testing.
