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 a series of 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".

[2] However, they differ significantly in the degree of support for these safety standards:[3] This computer hardware article is a stub.
