Hercules (processors)

Hercules is a line of ARM architecture-based microcontrollers from Texas Instruments built around one or more ARM Cortex cores. This "Hercules safety microcontroller platform" includes series microcontrollers specifically targeted for Functional Safety applications, through such hardware-base fault correction/detection features as dual cores that can run in lock-step, full path ECC, automated self testing of memory and logic, peripheral redundancy, and monitor/checker cores.

This line includes the TMS470M, TMS570 and RM4 families. These families were "Designed specifically for IEC 61508 and ISO 26262 safety critical applications". However, they differ significantly in the degree of support for these safety standards:
