Abstract
A prefetch processing apparatus includes a central-processing-unit monitor unit that monitors processing states of the central processing unit in association with time elapsed from start time of executing a program. A cache-miss-data address obtaining unit obtains cache-miss-data addresses in association with the time elapsed from the start time of executing the program, and a cycle determining unit determines a cycle of time required for executing the program. An identifying unit identifies a prefetch position in a cycle in which a prefetch-target address is to be prefetched by associating the cycle determined by the cycle determining unit with the cache-miss data addresses obtained by the cache-miss-data address obtaining unit. The prefetch-target address is an address of data on which prefetch processing is to be performed.
