    Abstract: A low-power memory access method and associated apparatus are provided. The apparatus includes a memory controller and a processing unit. The memory controller is coupled to a first memory and a second memory, and includes: a memory management circuit, for allocating physical memory addresses of the first memory and the second memory and controlling access of the first memory and the second memory; and a direct-memory-access (DMA) controller. The processing unit is for accessing the first memory and the second memory via the memory controller. When the apparatus is in an active mode, the memory management circuit copies a portion of data stored in the second memory to the first memory for use by the processing unit, and records dirty data information when the portion of data in the first memory differs from that in the second memory.

    Abstract: A computing system includes a multi-core processor and a core controller. The core controller is for: monitoring utilization of the multi-core processor; calculating a target performance index according to the utilization of the multi-core processor, a target utilization and a first performance index, wherein the first performance index is associated with a first entry of a dynamic voltage frequency scaling (DVFS) table that corresponds to a current setting for the multi-core processor; and selecting a second entry of the DVFS table that corresponds to a target-setting according to the target performance index and a second performance index that is associated with the second entry. The target-setting is used to configure the multi-core processor.
