Information processing apparatus, control method therefor, and computer-readable storage medium

摘要

There is provided a mechanism of preferentially using a memory layer which suffers a small influence of heat of an SOC die, based on the positional relationship between the SOC die and the memory layer, and decreasing the refresh frequency of the DRAM and a leakage current. To accomplish this, an information processing apparatus allocates, in order to execute an accepted job, a memory area for executing the job preferentially from a memory physically farthest from the SOC die among a plurality of memories, and then executes the job.

主权项

1. An information processing apparatus including an SOC die having a CPU and a WideIO memory device in which a plurality of memories are stacked on said SOC die, comprising:
an acceptance unit configured to accept a job; a memory control unit configured to allocate, in order to execute the job accepted by said acceptance unit, a memory area for executing the job preferentially from a memory physically farthest from said SOC die among the plurality of memories; and an execution unit configured to execute the job using the memory area allocated by said memory control unit.
