Functionally safe processor system

A method comprising:

• incrementing each of a plurality of functional safety (FUSA) monitoring counters upon detection of a functional safety (FUSA) event, wherein the plurality of FUSA monitoring counters includes a functional safety (FUSA) error counter, a functional safety (FUSA) warning counter and a reference time window for clearing, and wherein the plurality of FUSA monitoring counters is part of a hardware-based monitoring system;
• comparing the plurality of FUSA monitoring counters to a plurality of functional safety (FUSA) counter thresholds using a push methodology;
• generating at least one interrupt signal and sending the at least one interrupt signal to a FUSA control module if at least one of the plurality of FUSA monitoring counters exceeds at least one of the plurality of FUSA counter thresholds;
• and
• executing a state transition to a functional safety (FUSA) safe state using the push methodology based on the at least one interrupt signal.

An apparatus comprising:

• means for incrementing each of a plurality of functional safety (FUSA) monitoring counters upon detection of a functional safety (FUSA) event, wherein the plurality of FUSA monitoring counters includes a functional safety (FUSA) error counter, a functional safety (FUSA) warning counter and a reference time window for clearing, and wherein the plurality of FUSA monitoring counters is part of a hardware-based monitoring system;
• means for implementing the reference time window with a timer and a programmable timer threshold for reference time management;
• means for comparing the plurality of FUSA monitoring counters to a plurality of functional safety (FUSA) counter thresholds using a push methodology;
• means for generating at least one interrupt signal and sending the at least one interrupt signal to a FUSA control module if at least one of the plurality of FUSA monitoring counters exceeds at least one of the plurality of FUSA counter thresholds;
• and
• means for executing a state transition to a functional safety (FUSA) safe state using the push methodology based on the at least one interrupt signal.
