PERFORMANCE MONITORING IN HETEROGENEOUS SYSTEMS

Abstract:

Embodiments of apparatuses, methods, and systems for performance monitoring in heterogenous systems are described. In an embodiment, an apparatus includes a plurality of performance counters to generate a plurality of unweighted event counts; a weights storage to store a plurality of weight values, each weight value corresponding to an unweighted event count; a plurality of weighting units, each weighting unit to weight a corresponding unweighted event count based on a corresponding weight value to generate one of a plurality of weighted event counts; and a work counter to receive the weighted event counts and generate a measured work amount.
