DATA DEPLOYMENT DETERMINATION APPARATUS, DATA DEPLOYMENT DETERMINATION PROGRAM, AND DATA DEPLOYMENT DETERMINATION METHOD

摘要

A data deployment determination apparatus includes a correlation information creation processor that creates correlation information in which addresses indicating areas in a first memory are correlated with frequency information on memory accesses for the respective addresses, from trace information on a memory access to the first memory, a time reduction calculation processor that calculates, for each of the addresses, time reduction in memory accesses to data stored in the first memory based on the correlation information when data stored in the first memory is stored in a second memory which is a memory having a larger bandwidth than the first memory, and a data deployment determination processor that determines that first data stored in the address of which the time reduction is larger than the time reduction corresponding to second data stored in the address is to be stored in the second memory in preference to the second data.
