Abstract
A calculator includes a processing core and a cache. The cache includes a data memory that holds data transferred from a main memory and a cache controller that controls transfer of data between the main memory and the data memory. The cache controller is configured to calculate, upon occurrence of a cache miss, a cycle count requested for arithmetic processing on one unit amount of data based on a cache miss occurrence interval and a memory access latency requested, and update a prefetch distance based on the calculated cycle count and the memory access latency, the prefetch distance indicating a relative distance on the main memory between a location from which the one unit amount of data transferred from the main memory due to the cache miss and a location from which a next one unit amount of data is to be prefetched.
