DATA FLOW MONITORING IN A MULTIPLE CORE SYSTEM
An integrated circuit includes a functional core configured to execute functional logic instructions; a functional memory device coupled to the functional core; a safety core configured to execute safety check logic instructions; a monitored address memory device coupled to the functional core and the safety core, the monitored address memory device configured to store memory addresses to be monitored; and a first safety memory device coupled to the functional memory device and the safety core. When a value in one of the monitored memory addresses changes, the changed value of the one of the monitored memory addresses is stored in the functional memory device and in the first safety memory device. The safety core performs a safety check on the changed value of the one of the monitored memory addresses stored in the first safety memory device.
