Processor Monitoring Using Asynchronous Signatured Instruction Streams
J.B. Eifert, J.P. Shen · 2005
An on-ime munrlorrng approach for detecting transient errors in mumrple pracessor systems is mfroduced. This approach IS based off B scheme caIfed Asynchronous Srgnatured instruction Streams [ASS] A watchdog fype processor fs used as a rovrng monitor to check the correct control fjow of programs executing in the processors berng monilored. AN transient errors affecting the control ifow of appkaffon programs can be detected. This FI?O~~~O~NXJ scheme has been tmplemenfed for the MC68000 processor and a demonsrrafion sysfem hdS been designed and fs being buiif. Motivations
