Abstract
A computer-implemented method for of constrained carries on speculative counters includes providing one or more speculative counters having an upper portion of most significant bits partially embedded in a random-access memory (RAM) array, and a pre-counter portion external to the RAM array having a plurality of least significant bits. The one or more speculative counters are configured to count a plurality of events of interest during a processor core instruction execution. A carry output from the pre-counter portion to the RAM array is suppressed for a duration of a speculative event period.
