Use of MISR Output Streams for Diagnostics

Abstract

This paper describes a simple means for diagnosing failures by observing a compacted MISR output stream. While MISRs have been used in the industry for response compression, their use has often been seen as an impediment to diagnosis of failures. This paper shows how it is possible to use MISRs to perform a go/no-go failure test with very little data volume and to also use a compacted continuous stream of MISR output states to aid diagnosis.

“…To detect faults and errors in the computation of each PE, we use a hardware monitoring technique based on Multiple Input Signature Registers (MISRs). MISRs are specialized shift registers that generate signatures representing streams of input data [31], [32].…”
