Information processing apparatus and information processing method
摘要：
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).
摘要（中）：

在根据本发明的信息处理设备（1）中，GMCH（13）通过CPU总线（12）连接到CPU（11），并且ICH（15）通过一个 专用巴士（14）。 GMCH（13）包括图形控制器（131），其借用安装到存储卡（17）的存储器（171）的一部分以执行显示处理。 图形卡（19）可以连接到GMCH（13）。 在这种情况下，图形控制器（131）变为停止状态。 当图形卡（19）连接到GMCH（13）时，CPU（11）指示图形控制器（13）执行除显示控制处理之外的处理，例如MC和IDCT等处理。 结果，可以减少施加到CPU（11）的负载。
