Abstract
A performance analysis system includes a picker module and a calculation circuit. The picker module is placed in the processing device to capture a plurality of pieces of time information of a unit circuit of each of a plurality of tasks in the processing device during total execution time of processing the plurality of tasks. The calculation circuit performs an interval analysis operation on the time information. The interval analysis operation includes: calculating an overlap period between a current task and a previous task; and counting time occupied by the unit circuit during the total execution time of processing the tasks by the processing device according to a relation between the current time interval of the current task corresponding to the unit circuit and the overlap period.
