Abstract
A software program includes at least two performance levels. Each performance level has an associated processor utilization. Each performance level corresponds to optimization criteria, such as a quality of data processing performed by the software program. The performance level is selected to maintain processor utilization by the software program within constraints, such as a desired range of processor utilization and a minimum idle thread allocation.

A method of managing utilization of an integrated circuit (IC) processor, comprising:
- monitoring processor utilization by an adjustable software video encoder program running on a first thread, the adjustable video software encoder program having at least two different performance levels associated with a video quality of individual frames, wherein each performance level has a different associated IC processor utilization and said performance levels comprise video encoding levels corresponding to an encoder configuration;
- selecting a performance level corresponding to a video encoding level to achieve a highest possible video quality while maintaining an idle thread utilization above a minimum threshold selected to permit another software program to load and execute;
- and
- generating running estimates of processor utilization for previous instantiations of the adjustable software video encoder program to determine how much to adjust said performance levels.
