Abstract
A semiconductor device includes a plurality of cores, each including an instruction execution circuit and a first cache, and a second cache shared by the plurality of cores. In each of the cores, a number of completed instructions for each type of the instructions executed by the instruction execution circuit are counted, and an execution frequency for each type of instructions are calculated. Based on the execution frequencies, a cache line size preferable for use in the first cache in the core is selected. Based on the selected preferable cache line sizes for the cores, a cache line size used in the first caches and the second cache is determined.
