TL;DR: In this article, a video peripheral board for providing video I/O capabilities to a general purpose host computer is presented, consisting of a video device, a bus interface circuit, and control logic.
Abstract: A video peripheral board for providing video I/O capabilities to a general purpose host computer. The video peripheral board comprises a video I/O port configured to connect a video device, a bus interface circuit, and control logic. The bus interface circuit is configured to connect the video peripheral board into a system bus of the host computer, and is capable of becoming bus master of the system bus. The control logic is configured to control the bus interface circuit to effect transfer of video data between the video I/O port and storage of the host computer, the video data passing through the video I/O port in real time.

08 Dec 2014TL;DR: In this paper, a network device connected via a bus with a plurality of network devices includes an authentication unit that executes authentication based upon message authentication information included in data transmitted, via the bus, by one of the plurality of the network devices acting as a sender device.
Abstract: A network device connected via a bus with a plurality of network devices includes: an authentication unit that executes authentication based upon message authentication information included in data transmitted, via the bus, by one of the plurality of network devices acting as a sender device; and a processing unit that invalidates the data upon determining that unauthorized data have been transmitted by the sender device impersonating another network device among the plurality of network devices if the authentication fails.

18 Oct 2004TL;DR: In this paper, a breakpoint is made of where, within the data block structure, a break point will occur in the data being placed on the bus by a first source (e.g., the local or downstream data).
Abstract: In a memory system, multiple memory modules communicate over a bus. Each memory module may include a hub and at least one memory storage unit. The hub receives local data from the memory storage units, and downstream data from one or more other memory modules. The hub assembles data to be sent over the bus within a data block structure, which is divided into multiple lanes. An indication is made of where, within the data block structure, a breakpoint will occur in the data being placed on the bus by a first source (e.g., the local or downstream data). Based on the indication, data from a second source (e.g., the downstream or local data) is placed in the remainder of the data block, thus reducing gaps on the bus. Additional apparatus, systems, and methods are disclosed.

20 Nov 1995TL;DR: In this paper, the authors present a computer system optimized for real-time applications which provides increased performance over current computer architectures, which includes a standard local system bus, such as the PCI bus, and also includes a dedicated realtime bus or multimedia bus.
Abstract: A computer system optimized for real-time applications which provides increased performance over current computer architectures. The system includes a standard local system bus, such as the PCI bus, and also includes a dedicated real-time bus or multimedia bus. Thus multimedia devices such as video cards, audio cards, etc., as well as communications devices, transfer real-time data through a separate bus without requiring arbitration for the PCI bus. The computer system of the present invention thus provides much greater performance for real-time applications than prior systems. In various embodiments, multimedia devices transmit addressing and control information for a multimedia bus transfer either over the PCI bus or using a separate serial control channel. The multimedia bus may also comprise separate multimedia channels for different data types. Methods are also disclosed for transferring periodic multimedia data over the multimedia bus.

TL;DR: The serial bus as discussed by the authors allows a bus master to communicate with a variety of semiconductor devices that support serial interface standards, such as JTAG, SPI, and I 2 C. The serial bus allows a single bus master can control and observe a JTAG-compatible semiconductor device, an SPI-compatible device and an I 2C compatible device over the serial bus.
Abstract: A serial bus is provided that supports multiple data transmission protocols. The serial bus allows a bus master to communicate with a variety of semiconductor devices that support a variety of serial interface standards. As a result, a single bus master may control and observe a JTAG-compatible semiconductor device, an SPI-compatible semiconductor device and an I 2 C compatible semiconductor device over the serial bus.
