Abstract
A data transfer control apparatus controls data transfers between different modules, and includes a module DMA controller configured for a predetermined module, a function DMA controller that provides a function absent in the module DMA controller, and a temporary memory coupled to the module DMA controller and the function DMA controller. When the temporary memory is input with data acquired by the module DMA controller from the predetermined module in order of acquisition, the temporary memory outputs the acquired data to the function DMA controller in order of input. When the temporary memory is input with data to be transferred to the predetermined module from the function DMA controller, the temporary memory outputs the data to be transferred to the module DMA controller in order of input.
