    摘要: 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.

    摘要: 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.

    摘要: In the case where, in a WDM-PON system, a high-output optical signal or a pseudo signal for illegal access by a hostile user, or an optical signal with a wavelength which is not assigned from an OLT is input to an ONU-side optical fiber, the quality of communications for other users is possibly affected and a receiver on the station side is possibly destroyed. By providing an optical blocking unit at a position near an ONU-side optical splitter of an optical branching unit, in the case where input of an extraordinary optical signal is detected, an optical route into which the extraordinary optical signal is input is blocked, so that the input of the extraordinary optical signal to an OLT and optical lines shared by plural users can be preliminarily blocked.
