Abstract:
1. An information processing apparatus having a main processor which exercises centralized control on the entire apparatus and a second processor which performs graphic processing, the apparatus comprising: a main memory at which texture data intended for the graphic processing is stored first, a DMA controller which is operable to transfer m (m is an integer, m>1) pieces of texture data simultaneously from the main memory according to a given command list comprising a plurality of commands; and a graphic memory having buffers to which the texture data is transferred from the main memory, the number of the buffers being greater than the number of the texture data which can be transferred simultaneously by the DMA controller, wherein the command list is configured such that there is at least one buffer which is not designated as a transfer destination of the texture data by switching the set of the buffers designated as the transfer destination of m pieces of texture data from the main memory according to stages of the graphic processing in the second processor, and that while the texture data is transferred to the buffers in accordance with the command list, an object data is transferred from the main processor to the graphic memory in parallel.
