Measuring performance associated with processing instructions based on counters for different events

A non-transitory computer readable medium comprising a circuit representation that, when processed by a computer, is used to program or manufacture an integrated circuit comprising:

• a plurality of counters configured to count events associated with processing instructions in a pipeline of a processor, wherein a first counter of the plurality of counters is configured to count a first event and a second counter of the plurality of counters is configured to count a second event different from the first event;
• and
• trigger circuitry configured to trigger a performance measurement for a first instruction based on an AND selection of the first counter meeting a corresponding first predefined value and the second counter meeting a corresponding second predefined value, wherein triggering the performance measurement causes the plurality of counters to reset, wherein the performance measurement comprises counting events associated with processing the first instruction, and wherein the first counter and the second counter used for the AND selection are reused to count the events associated with processing the first instruction.
