Abstract

Aspects of the disclosure relate to a processor core including an execution unit and a usage ratio controller. The execution unit is operable for executing a command forwarded to the execution unit. The usage ratio controller is operatively coupled with the execution unit. The usage ratio controller is operable for controlling a usage ratio of the execution unit. The usage ratio corresponds to the fraction of an observation time during which the execution unit is executing commands of an application. Other aspects of the disclosure relate to a method for detecting or analyzing a bottleneck in a processor core for a given application. The method includes controlling a usage ratio of at least one execution unit of the processor core and measuring the resulting application performance.
