ABSTRACT:
An integrated circuit includes a plurality of functional blocks. Utilization information for the various functional blocks is generated. Based on that information, the power consumption and thus the performance levels of the functional blocks can be tuned. Thus, when a functional block is heavily loaded by an application, the performance level and thus power consumption of that particular functional block is increased. At the same time, other functional blocks that are not being heavily utilized and thus have lower performance requirements can be kept at a relatively low power consumption level. Thus, power consumption can be reduced overall without unduly impacting performance.
