Abstract: The present invention relates to an information processing apparatus, an information processing method, and a program capable of simplifying an interrupt processing and reducing a time necessary to the interrupt processing. An interrupt generation unit 140 generates an interrupt signal. An interrupt status holding unit 142 stores an interrupt status showing a cause of generation of the interrupt signal. An interrupt status supply unit 141 supplies an interrupt status stored by an interrupt status holding unit to a RAM and causes the RAM to store it. A CPU executes a predetermined processing in response to the interrupt status stored to the RAM. The present invention can be applied to, for example, a network card.

Abstract: Disclosed herein is an information processing apparatus that transfers information, using direct memory access (DMA), between a first storage section in an information processing system and a second storage section in an information transfer system. The information processing system includes the first storage section for storing the information, and a control section. The information transfer system includes: the second storage section for storing descriptor information indicating the location at which the information is stored in the first storage section and the size of the information; and a DMA transfer section for DMA transferring the information between the first storage section and the second storage section based on the descriptor information. The DMA transfer section DMA transfers the descriptor information concerning the DMA transferred information from the second storage section to the first storage section. The control section loads the descriptor information from the first storage section.

Abstract: An information processing device is provided. The information processing device includes a frame acquiring unit for acquiring a frame using a signal transmitted via a network, a computing unit for computing a check sequence on the basis of data included in the frame, a checking unit for checking whether the frame is corrupted by checking whether the check sequence coincides with a check sequence added to the frame in advance, a storing unit for storing a table that is a list of check sequences computed in advance on the basis of a plurality of pieces of data representing addresses of frames to be received by the information processing device, and a determining unit for determining whether the frame should be received by determining whether a check sequence computed by the computing unit on the basis of data representing a destination address of the frame coincides with any one of the check sequences included in the table.

Abstract: A communication apparatus is provided. The communication apparatus includes a transmission unit adapted to transmit data via a network, a receiving unit adapted to receive data supplied via the network, an interface unit adapted to supply to-be-transmitted data to the transmission unit and extract particular information from data received by the receiving unit, and a control unit configured to control an operation state of the interface unit.
