Programmable state machine for a hardware performance monitor

A system, comprising:

• a processor comprising a set of logic circuits associated with a state machine;
• and
• a memory included in the processor;
• wherein the processor:
• receives, via the set of logic circuits, a set of one or more signals;
• generates, via the set of logic circuits, a first input based on the set of one or more signals and a first input mask associated with a first state transition condition, wherein the first input mask and the first state transition condition are stored in a first data entry in the memory;
• determines, via the set of logic circuits, based on the first input and a current state, that the first state transition condition is satisfied;
• and
• in response to determining that the first state transition condition is satisfied, transitions, via the set of logic circuits, the processor from the current state to a first state, wherein the first state is stored in the memory and associated with the first state transition condition,
• wherein the first state transition condition, the current state, and the first state are associated with the state machine.

A non-transitory computer-readable medium storing program instructions that, when executed by a processor, cause the performance monitor to perform the steps of:

• receiving a set of one or more signals;
• generating a first input based on the set of one or more signals and a first input mask associated with a first state transition condition, wherein the first input mask and the first state transition condition are stored in a first data entry in a memory associated with a performance monitor;
• determining, based on the first input and a current state, that the first state transition condition is satisfied;
• and
• in response to determining that the first state transition condition is satisfied, transitioning the performance monitor from the current state to a first state, wherein the first state is stored in the memory and associated with the first state transition condition.
