Processor-based system including a processing unit for dynamically reconfiguring micro-architectural features of the processing unit in response to workload being processed on the processing unit

A processor-based system for dynamically reconfiguring micro-architectural features, comprising:

• a first processing unit, the first processing unit comprising one or more micro-architectural features;
• and
• a processing unit control unit configured to:
• receive a plurality of signals from the first processing unit, wherein the plurality of signals are indicia of a workload being processed by the first processing unit;
• and
• in response to at least one of the plurality of signals:
• determine whether performance or power consumption of the first processing unit may be improved;
• and
• in response to determining that the performance or the power consumption of the first processing unit may be improved:
• trigger the first processing unit to modify the one or more micro-architectural features,
• the first processing unit, in response to being triggered by the processing unit control unit, configured to:
• modify the one or more micro-architectural features, wherein:
• the indicia of the workload includes an indication of a streaming application launch;
• and
• the processing unit control unit configured to, in response to at least one of the plurality of signals, trigger the first processing unit to modify the one or more micro-architectural features is further configured to:
• trigger the first processing unit to set a prefetch mode to a conservative mode.
