Performance monitoring in heterogeneous systems

A method comprising:

• programming a plurality of performance counters to generate a plurality of unweighted event counts;
• programming a weights storage to store a plurality of weight values, each weight value corresponding to an unweighted event count;
• weighting each of the plurality of unweighted event counts based on a corresponding weight value to generate one of a plurality of weighted event counts;
• and
• generating a measured work amount based on the plurality of weighted event counts.

A system comprising:

• a system memory to store a task scheduler;
• a first core of a first type;
• a second core of a second type, wherein the second type is different from the first type;
• 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, wherein the measured work amount is to be used by the task schedule to schedule a task to one of the first core and the second core.
