System and method of monitoring performance of an electronic device

A system of monitoring performance of an electronic device, comprising:

• a plurality of performance monitoring circuits included in an electronic device;
• wherein the plurality of performance monitoring circuits are configured to generate a plurality of monitor output signals including performance data of the electronic device;
• a monitoring bus configured to receive the plurality of monitor output signals and generate a bus output signal by interleaving the performance data included in the plurality of monitor output signals;
• and
• an embedded trace router configured to receive the bus output signal and store, in a memory de-vice included in the electronic device, the performance data included in the bus output signal,
• wherein the monitoring bus includes a plurality of stages configured to sequentially interleave and transfer the performance data to the embedded trace router, and each stage of the plurality of stages includes one or more serial interconnect circuits.

A method of monitoring performance of an electronic device, comprising:

• generating, using a plurality of performance monitoring circuits distributed in an electronic device, a plurality of monitor output signals including performance data of the electronic device;
• generating, using a monitoring bus configured to receive the plurality of monitor output signals, a bus output signal by interleaving the performance data included in the plurality of monitor output signals;
• and
• storing, using an embedded trace router configured to receive the bus output signal, in a memory device included in the electronic device, the performance data included in the bus output signal,
• wherein generating the plurality of monitor output signals includes:
• packetizing the performance data collected during a unit time by each performance monitoring circuit of the plurality of performance monitoring circuits to output a plurality of packets corresponding to a plurality of unit times one by one;
• and
• dividing each packet into a plurality of slices to sequentially transfer the plurality of slices to the monitoring bus.
