Methods and apparatus for bridged data transmission and protocol translation in a high-speed serialized data system

摘要

An apparatus for transmitting data across a high-speed serial bus includes an IEEE 802.3-compliant PHY having a GMII interface; an IEEE 1394-compliant PHY in communication with the IEEE 802.3-compliant PHY via a switch; the switch determining whether data transmission is to be routed to the IEEE 802.3-compliant PHY or the IEEE 1394-compliant PHY; a first connection, the first connection for transmitting data between a device and the IEEE 802.3-compliant PHY; and a second connection, the second connection for transmitting data between a device and the IEEE 1394-compliant PHY.

主权项

1. An apparatus comprising:
a first interface operating according to a first protocol, the first interface being configured to operate within a first clock domain; at least one second interface, the at least one second interface adapted to operate according to a second protocol and within a second clock domain; a translation apparatus in signal communication with both the first and at least one second interfaces and comprising an elasticity buffer, the elasticity buffer configured to insert or remove one or more illegal symbols to compensate for a difference between the first and second clock domains; a bridging apparatus adapted to provide logical network addressing for devices connected to the first interface and the at least one second interface; and apparatus, responsive to a negotiation, enabling at least one of the translation apparatus and/or the bridging apparatus.
