1.2 Dual CPU Core

The purpose of the Dual-Core LockStep CPU is to achieve high diagnostic coverage and meet strict timing requirements. In this configuration, two identical CPUs execute the same program in parallel, with their internal state being continuously compared by a DCLS comparator. Any mismatch between the CPUs is reported as an error and will issue a machine check reset.

Additionally, the CPU has built-in illegal OPCODE and illegal address detection.
