An information processing apparatus includes a controller configured to obtain the number of files to be written to a storage medium whose storage area configured in units of a predetermined block and whose stored data is erased in units of the predetermined block, and to determine a policy for selecting, based on the obtained number of files, the block to which the one or more files are to be written.

Information processing apparatus and method for writing data to a storage medium

An electronic apparatus that includes a CPU and at least one device and that is identical to or different from an electronic apparatus in which the CPU is capable of simultaneously executing multiple applications. The electronic apparatus includes: a determiner that determines usage rates of the CPU and the device for each application being executed, on the basis of at least one of statistical information and log information of the CPU and the device; a divider that determines proportions of power consumptions of the CPU and the device relative to a power consumption of the entire electronic apparatus; and an estimator that estimates a proportion of a power consumption for each application relative to the power consumption of the entire electronic apparatus, on the basis of the determined usage rates and the determined proportions.

Calculating power consumption for each application executed by an electronic apparatus

There is provided a memory control device including a device driver that executes writing or reading of data to/from a main storage unit and temporary writing or reading of data to/from a cache unit including a plurality of cache blocks, and a control unit that issues an instruction for writing or reading of data of a file system to/from the main storage unit or the cache unit to the device driver. The control unit may notify priority information about a priority for data storage into a logical block to which the cache block is associated to the device driver.
