Information processing apparatus and method to control memory access and computer-readable recording medium having stored therein control program to control memory access
Abstract:
An information processing apparatus includes: a first memory; a second memory different in processing speed from the first memory; and a processor including: a memory controller that is coupled to the first memory and the second memory and that controls an access to the first memory and an access to the second memory; and a plurality of controllers that access to the first memory or the second memory. The processor is configured to suppress a writing frequency of data into the second memory by controlling one or more first controllers that access the second memory among the plurality of controllers in accordance with a result of monitoring a state of writing the data into the second memory.
