DEVICE OF COMMUNICATION INTERFACES SpaceWire

摘要

The useful model of "the device of communication interfaces SpaceWire" refers to digital computer technology, namely to high-speed local computer networks for on-board complexes.;The technical result is the creation of network structures for the collection and transmission of data from a variety of sensors based on SpaceWire technology by connecting two-port devices of the SpaceWire communication interfaces to each other. A sensor controller can be connected to each device via the ANV bus interface. At the same time, it is possible to realize the transfer of data from an arbitrary set of sensors to one SpaceWire port, completely using its bandwidth to load the data processor connected to it as completely as possible. The device supports the switching of SpaceWire packets and the RMAP transport layer protocol for device configuration and sensor controller data access.;The closest to the claimed device is the communication interface device (RF patent for invention No. 2460124), which is a SpaceWire port and contains a data output unit, a data receiving unit, a control unit, a data flow control and communication unit.;The technical result is achieved by the fact that a second SpaceWire port, a packet data switching unit, two transmission rate control units, two transmission timing generation units, a mode / state registers block, a register of routing registers, a packet selector, a RMAP protocol driver, an ANV interface controller Master and controller of the ANV Slave interface and new connections. 1 z.s. f-ly, 12 yl., 26 table.
