Error identification and data recovery in MISR-based data compaction
Xiaoling Sun, W. Tutak · 2002
This paper introduces a novel data recovery scheme for multiple data streams and multiple errors in MISR (multiple input shift register) based parallel data compaction. Utilizing existing BIST resources with an additional MISR, it is capable of identifying any number of errors in any two input data streams, and recovering the information bits lost during signature compaction.
