发明名称 Method and apparatus for using dynamic workload characteristics to control CPU frequency and voltage scaling
摘要 An electronic system may include a memory storing processor-executable program code and a processor in communication with the memory and operative in conjunction with the stored program code to determine a number of retired instructions and a number of input/output queue events for a workload and to determine if a performance characteristic is within a desired performance range based at least in part on the number of retired instructions and the number of input/output queue events. If the performance characteristic is within the desired performance range, the processor may be further operative in conjunction with the stored program code to determine an amount of time on die and an amount of time off die for the workload, to determine if a phase shift occurred based on the amount of time on die and the amount of time of die, and, if the phase shift occurred, to determine a new target frequency for a processor to execute the workload.
