Abstract: A processing system includes a bus and a processor whose core is constrained to have one or more core clock signal frequencies no lower than a predetermined multiple of the lowest of one or more bus clock signal frequencies. In a power-save mode, the processor is able to generate one or more core clock signals at frequencies such that the lowest core clock signal frequency is lower than the predetermined multiple of the lowest of the one or more bus clock signal frequencies in performance mode. The processor is able to achieve this by generating the one or more bus clock signals so that the lowest of the bus clock signal frequencies in power-save mode is lower than the lowest of the bus clock signal frequencies in performance mode.

Abstract: Apparatus and methods to adaptively throttle accesses to memory employ a masking tool to specify the percentage of memory bandwidth available for access. The apparatus applies the mask and monitors the number of memory accesses during a throttle-monitoring window. If the number of memory accesses during the throttle-monitoring window exceeds or is fewer than the percentage of memory bandwidth specified by the mask, access to the memory continues until the end of the throttle-monitoring window and at the end of the throttle-monitoring window the apparatus selects the next lower mask for a lower memory bandwidth allocation or selects the next higher mask for a higher memory bandwidth allocation, respectively.
