5 Nov 2002TL;DR: In this article, a Fibre Channel private loop device interconnect system is described, where the Fibre channel is connected to two or more Arbitrated Loops containing, or adapted to contain, one or more private loop devices.
Abstract: Methods and apparatus for Fibre Channel interconnection is provided between a plurality of private loop devices through a Fibre Channel private loop device interconnect system. In the preferred embodiments, the Fibre Channel private loop device interconnect system is a fabric or an intelligent bridging hub. In one aspect of this invention, a Fibre Channel private loop device is connected to two or more Arbitrated Loops containing, or adapted to contain, one or more private loop devices. Preferably, the interconnect system includes a routing filter to filter incoming Arbitrated Loop physical addresses (ALPAs) to determine which Fibre Channel frames must attempt to be routed through the fabric. Numerous topologies of interconnect systems may be achieved. In another aspect of this invention, a method is provided for implementing a logical loop of private loop devices by segmenting the logical loop into a plurality of sets, assigning each set to a physical Arbitrated Loop and connecting the Arbitrated Loops to a Fibre Channel private loop device interconnect system. Additional methods are provided for restricting attached devices to Arbitrated Loop physical addresses within certain ranges. Additionally, methods are provided for resetting hosts, the method generally comprising the steps of detecting the addition of a storage device to a first Arbitrated Loop, and thereafter, resetting the Arbitrated Loop or loops on which a host or hosts reside on second Arbitrated Loop. Methods for operation with use of SCSI initiators generate a link service reject when no address match is found, or when an address match is found, but where no device with the destination ALPA exists on the Arbitrated Loop corresponding to the destination.

TL;DR: In this article, a hybrid pipelining device for video coding is described, which comprises a prefetched data acquisition device, a mode selector, a reconstruction loop device and an entropy coder.
Abstract: The invention discloses a hybrid pipelining device used for video coding, which comprises a prefetched data acquisition device, a mode selector, a reconstruction loop device and an entropy coder. The reconstruction loop device comprises an intra-frame predictor, an inter-frame predictor, a differential reconstruction device and a deblock filter; data of the same macro block is processed through the prefetched data acquisition device, the mode selector, the reconstruction loop device and the entropy coder sequentially in different timeslices; and in the same timeslice, the prefetched data acquisition device, the mode selector, the reconstruction loop device and the entropy coder process the data of four different macro blocks. The hybrid pipelining device increases the PDR, reduces the area of a memory, and serves the purposes of high definition and real-time coding.

TL;DR: In this article, the authors proposed the utility model for the backup of an Ethernet ring network device with two slave devices adjacent to each other, where one of the slave devices acts as a main device for backup in the backup domain and the other slave device works as a slave device for the main domain.
Abstract: The utility model discloses an Ethernet ring network device with backup files, comprising a main device and two slave devices adjacent to each other. A backup domain is arranged in the Ethernet ring network; one of the two slave devices works as a main device for backup in the backup domain, and the other slave device works as a slave device for backup in the backup domain. Through a link arranged between the main device for backup and the slave device for backup, the main device for backup, the slave device for backup and the main device form a ring network in the backup domain. An uplink port is arranged on the main device for backup. The utility model also discloses a backup method for the main device in the Ethernet ring network. The utility model has the advantages of adding a main device for backup based on the prior art of the Ethernet ring network, and adding a backup domain to monitor the state of the main domain, thus achieving the valid backup for the main device in the Ethernet ring network.
