Electronic device, a method of controlling an electronic device, and system on-chip

Method for controlling an electronic device having at least one processing circuit for processing at least one application, comprising the steps of:

• controlling the at least one application performed by the at least one processing circuit,
• detecting a build-up of workload of the at least one processing circuit due to the at least one application,
• detecting a decrease of the workload of the at least one processing circuit, and
• controlling an operating frequency and an operating voltage of the at least one processing circuit in dependence on one of the detected workload build-up and the detected workload decrease due to the at least one application,
• increasing the operating frequency and the operating voltage if a workload build-up has been detected, wherein the operating frequency is arranged to be decreased at a rate that matches a rate of the workload decrease due to the at least one application, wherein the rate of the workload decrease due to the at least one application is determined during an initial or first run of the at least one application and the determined rate of the build-up is used during subsequent start-ups of the at least one application for the purpose of decreasing the operating frequency and the operating voltage when the workload build-up is detected.

System on chip, comprising:

• at least one processing circuit configured and arranged to process at least one application,
• an operating system configured and arranged to control the at least one application performed by the at least one processing circuit,
• at least one workload build-up detector configured and arranged to detect a build-up of the workload of the at least one processing circuit due to the at least one application,
• at least one power management unit configured and arranged to control an operating frequency and an operating voltage of the at least one processing circuit in dependence on the detected workload build-up due to the at least one application, and
• wherein the power management unit is configured and arranged to increase the operating frequency and the operating voltage when a workload build-up has been detected, wherein the operating frequency is arranged to be increased at a rate that matches a rate of the build-up of the workload due to the at least one application, wherein the rate of the build-up of the workload due to the at least one application is determined during an initial or first run of the at least one application and the determined rate of the build-up is used during subsequent start-ups of the at least one application for the purpose of increasing the operating frequency and the operating voltage when the workload build-up is detected.
