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.
