Isolated safety region of a system on a chip

A system comprising:

• a first hardware component to perform one or more control operations associated with a machine;
• and
• a second hardware component external to and electrically isolated from the first hardware component, the second hardware component to perform one or more safety-related operations associated with the machine, wherein the second hardware component is capable of satisfying a higher safety level than the first hardware component based at least on the second hardware component being external from the first hardware component.

A method comprising:

• performing one or more first operations of a first type using first processing circuitry capable of achieving a first safety integrity level;
• and
• performing one or more second operations of a second type using second processing circuitry capable of achieving a second safety integrity level higher than the first safety integrity level, wherein the second safety integrity level is achievable due to the second processing circuitry being isolated electrically from the first processing circuitry.
