摘要： An information processing system is configured such that which when an application handling multimedia, especially, moving images is performed by an information processor such as a personal computer, a sufficient processing performance is realized with the conventional CPU and bus capabilities. The information processing system includes a bus adaptor or bus converter for connecting a CPU bus and a system bus. The bus converter includes an operation processing unit (ALU) capable of performing a portion of an operating function performed by the conventional CPU or a portion of an operating function performed by an image processing board connected to the system bus, whereby the bus converter takes over a portion of a processing to be performed by the CPU or I/O module. Thereby, an overhead time for data transfer through the buses is reduced so that the total performance of the system is improved. Also, since a processing unqualified for the CPU, for example, a bit operation can be performed by a dedicated hardware, the information processing performance is improved.
