Hardware module integrity during run-time is a critical functional safety requirement. Hardware Redundancy implemented by the lockstep CPU architecture (two CPUs executing the same function and the output of the CPUs are continuously compared) is a proven method for achieving high diagnostic coverage for both permanent and transient faults. The Lockstep Comparator Module (LCM) is implemented to compare output from the C28x CPU to detect permanent and transient faults.
The LCM implements the following features:
Figure 7-3 shows the LCM block diagram.
