DYNAMIC CLOCK VOLTAGE SCALING (DCVS) BASED ON APPLICATION PERFORMANCE IN A SYSTEM-ON-A-CHIP (SOC), AND RELATED METHODS AND PROCESSOR-BASED SYSTEMS

摘要

Dynamic clock voltage scaling (DCVS) based on application performance in a system-on-a-chip (SOC), and related methods and processor-based systems are disclosed. In this regard, in one embodiment, a method of providing an application-specific DCVS in a SOC is provided. The method comprises receiving performance data corresponding to at least one performance characteristic of a SOC indicative of an execution performance of an application executing on the SOC. The method also comprises storing the performance data for the application executing on the SOC. The method further comprises, responsive to executing the application on the SOC, determining an application-specific DCVS setting for the application based on the performance data, and setting a DCVS parameter of the SOC based on the determined application-specific DCVS setting for the application. In this manner, an optimal DCVS setting is provided for the SOC to optimize computing resources, thus improving perceived performance of the application.
