Abstract
A microcontroller having error injection circuitry is provided. The microcontroller may include one or more operational components, and an error injection circuity operatively coupled to the one or more operational components. The error injection circuitry may autonomously inject one or more errors into the one or more operational components, and guard one or more error channels associated with the one or more operational components during the injection of the one or more errors.
Claims20
A microcontroller comprising:
- one or more operational components;
- and
- an error injection circuity operatively coupled to the one or more operational components, wherein the error injection circuitry is to:
- autonomously inject one or more errors into the one or more operational components;
- and
- guard one or more error channels associated with the one or more operational components during the injection of the one or more errors.
3 more elements
A method comprising:
- autonomously injecting, by an error injection circuitry, one or more errors into one or more operational components of a microcontroller;
- and
- guarding, by the error injection circuitry, one or more error channels associated with the one or more operational components during the injection of the one or more errors.
An apparatus comprising:
- an error injection circuitry;
- and
- a fault detection time interval (FDTI) timer;
- wherein the error injection circuitry is configured to:
- inject one or more errors into one or more operational components of a microcontroller in response to a time interval of the FDTI timer elapsing;
- and
- guard one or more error channels associated with the one or more operational components during the injection of the one or more errors.
