Assigning wideio memories to functions based on memory access and acquired temperature information

摘要

Temperature information of each of a plurality of memories of a WideIO memory device is acquired. In a case that the execution of a function is designated, a memory to be used by a function module corresponding to the function is determined based on the memory access amount of the function module corresponding to the function and the acquired temperature information of the plurality of memories.

主权项

1. An information processing apparatus having a WideIO memory device stacked on a System On a Chip (SOC) die including a CPU, the apparatus comprising:
a plurality of memories of the WideIO memory device; a temperature acquisition unit configured to acquire temperature information of each of the plurality of memories of the WideIO memory device; a plurality of function modules configured to execute functions, wherein each function module executes a function by using each of the plurality of memories; a determination unit configured to determine, in a case that execution of a function is designated, a memory to be used by a function module corresponding to the function, based on a memory access amount of the function module corresponding to the function and the temperature information of the plurality of memories acquired by the temperature acquisition unit; and a storage unit configured to store memory access amounts of the plurality of function modules, a memory access amount relative ratio of the plurality of function modules, and a processability relative ratio of the plurality of function modules, and
wherein the determination unit further determines a memory at a lowest temperature among unused memories, in descending orders of memory access amount relative ratio and processability relative ratio stored in the storage unit, as the memory to be used by the function module corresponding to the function.
