Information processing apparatus having first DMA controller and second DMA controller wherein selection circuit determines which DMA will perform data transfer based on higher data transfer performance

摘要

Provided is an information processing apparatus and method of controlling same in which, when data transfer is performed among a plurality of control circuits, which control circuit is used to execute data transfer is controlled appropriately based on the transfer conditions of data transfer. To accomplish this, the apparatus has first and second control circuits, a request for data transfer performed between the first and second control circuits is acquired, the transfer conditions of the acquired data transfer are analyzed and which of the first and second control circuits is to execute the data transfer is selected.
