From the systems software point of view, the dual core lockstep approach has clear advantages. Abort handlers can detect cpu faults, and reject/restart data processing operations, using normal software development methodologies. It would be nice having a discussion on the abort handlers for the RM48 to detect and recover from cpu faults, and use of the CRC hardware for data structure signoff and protection.
