Arrangement and method for controlling power modes of hardware resources

摘要

A circuit arrangement and method of executing program code which utilize power control instructions capable of dynamically controlling power dissipation of multiple hardware resources during execution of a program by a processor. The processor configured to process such power control instructions and to maintain the power modes of the multiple hardware resources to that specified in an earlier-processed power control instruction, such that subsequently-processed instructions will be processed while the power modes of the multiple hardware resources are set to that specified by the earlier-processed power control instruction.
