Abstract
A performance evaluation apparatus and a performance evaluation method are provided. The performance evaluation method includes: detecting multiple access commands of a memory controller for page miss so as to identify at least one page-missed command from the access commands; calculating an interval between the at least one page-missed command and a last conflict command to serve as a conflict command interval, wherein the last conflict command conflicts with the at least one page-missed command; and evaluating performance of the memory controller according to the conflict command interval.
