    摘要: The present invention provides a means for preventing execution of a transaction such as main storage access from obstruction by bus competition with low-speed IO access and improving the bus occupation efficiency. The present invention includes a first bus, a second bus, a plurality of modules connected to both buses, a bus conversion means for performing protocol conversion of information between both buses, a bus arbiter for arbitrating a bus occupation right request of a bus master, and a storage means for storing access data up to a predetermined amount when the access destination is a predetermined module. Each bus master outputs access destination information and when the bus arbiter judges that one of the bus masters issues a bus occupation right request when it performs an access operation, the bus arbiter refers to the access destination information and the data storage status of the storage means and decides whether or not to give a bus occupation right to the bus master.

    摘要: An information processing apparatus with a hierarchized bus structure having a system bus connected to central processing units and cache memories and an I/O bus connected to I/O devices. In response to a DMA request from the I/O device, a memory controller connected to both buses and to a main memory compares previous snoop addresses stored in a buffer memory of the memory controller with a current address contained in the DMA request to check whether the current DMA request is coincident with the past snoop process. If the comparison indicates a coincident snoop process, a snoop access process request is inhibited to be output to the system bus and cache memory. With this operation, the number of snoop accesses for DMAs to the same block of the cache memory can be reduced and a time during which the system bus is occupied can be shortened, to thereby improve the system performance.

    摘要: A video-phone call with a portable video-phone terminal is enabled for a cellular phone which has not video-phone service provided, by making use of cameras and display devices placed on the street. For a video-phone call to a portable video-phone terminal, a media converter in a service center distributes data so as to send video data to a public communication terminal on the street, and voice data to a cellular phone without video recording/reproducing capability. A call agent in a service center issues an ID in response to a request from the cellular phone without video recording/reproducing capability on voice call. This ID may be received by a service center via a detector such as a sensor deployed on the street, to provide a video-phone service by using a public communication terminal on the street in the vicinity of the detector.

    摘要: A synchronous data transfer system includes an oscillation circuit and a plurality of nodes connected to the oscillation circuit. Each node includes at least an internal logic circuit. Each of the nodes outputs a phase reference signal indicating phase of the clock signal, data processed by the internal logic circuit in response to the phase reference signal, and a transfer end signal indicating an end of transferring the data, respectively, in synchronism with the clock signal. A phase reference signal bus is connected to each node. A data bus is connected to each node for transmitting the data and a transfer end signal bus is connected to each node for transmitting the transfer end signal. A sender node includes a sending unit for sending data to a receiver node with a delay after the phase reference signal transmitted to the phase reference signal bus by the sender node, and sending simultaneously the transfer end signal to the receiver node. The receiver node includes a selecting unit for converting the phase reference signal into phase information to select a clock signal having a predetermined phase based on the received clock signal and a receiving unit for receiving data from the sender node using the selected clock signal.
