Abstract
Recording a trace of code execution using reference bits in a processor cache. A computing device comprises processing units and a shared cache. The shared cache includes a plurality of cache lines that is each associated with a plurality of accounting bits, which each includes a reference bits portion. Stored control logic uses these reference bits to log a second read operation by a second processing unit in reference to an already logged first read operation by a first processing unit.
