Abstract: A memory access latency estimation method includes measuring a first access latency of a first access operation of a first memory, measuring a plurality of first indexes of the first memory corresponding to the first access operation, using a plurality of first coefficients and the plurality of first indexes to perform a first weighted calculation to generate a first estimated latency, adjusting the plurality of first coefficients to generate a plurality of updated first coefficients, using the plurality of updated first coefficients and the plurality of first indexes to perform the first weighted calculation to adjust the first estimated latency for the first estimated latency to approximate the first access latency, and using the plurality of updated first coefficients and a plurality of second indexes of the first memory to perform a second weighted calculation to generate a second estimated latency for a second access operation.

Abstract: An idle time prediction method for a system includes obtaining n idle durations corresponding to n time points, determining if the n idle durations are of a normal distribution, generating a probability according to m idle states corresponding to m idle durations of the n idle durations if the n idle durations are not normally distributed, selecting a predicted idle state according to the probability, and controlling the system to enter the predicted idle state, where n and m are integers larger than one, and m≤n.

Abstract: A method of dynamic random access memory (DRAM) resource control for a DRAM manager of an electronic device is disclosed. The method comprises receiving at least one respective request message from at least one DARM user of the electronic device, each request message indicating required power information requested by the DRAM user sending the request message, and determining the DRAM to operate in one of a plurality of predetermined DRAM resource statuses respectively corresponding to a plurality of power levels according to the required power information respectively indicated by the at least one request message.
