Abstract: A CPU control method for controlling a first CPU and a second CPU The method comprises: (a) applying the first CPU to execute a first group of codes comprising at least one code if the first CPU is operating to perform a first function; and (c) applying the second CPU to execute a second group of codes comprising at least one code if the second CPU is operating to perform the first function. The first group of codes is optimized for the first CPU, the second group of codes is optimized for the second CPU and the first group of codes comprises at least one code different from the code for the second group of codes.

Abstract: A computing system performs an environment-aware cache flushing method. When a processor in the system receives a signal to flush at least a portion of the caches to the system memory, the processor determines a flushing mechanism among multiple candidate flushing mechanisms. The processor also determines one or more of the active processors in the system for performing the flushing mechanism. The determinations are based on the extent of flushing indicated in the signal and a runtime environment that includes the number of active processors. The system then flushes the caches to the system memory according to the flushing mechanism.
