Abstract:
In an information processing apparatus (1) according to the invention, a GMCH (13) is connected to a CPU (11) through a CPU bus (12), and an ICH (15) is connected to the GMCH (13) through a dedicated bus (14). The GMCH (13) includes a graphics controller (131) which borrows a part of a memory (171) mounted to a memory card (17) in order to execute display processing. A graphics card (19) can be connected to the GMCH (13). In this case, a graphics controller (131) becomes a stop state. While the graphics card (19) is connected to the GMCH (13), the CPU (11) instructs the graphics controller (13) to execute processing other than display control processing, for example, processing such as MC and IDCT. As a result, it is possible to reduce a load applied to the CPU (11).
