Abstract
A technique to reduce false error detection in microprocessors within a redundant multi-threaded computing environment. A pi bit is propagated with at least two instructions through an instruction flow path. Results of executing the instruction are compared to see if an error has occurred and if so, the pi bits are examined to determine which instruction contains the error.
