Embodiment Construction

[0022] The 10GbE proposal presented in the IEEE draft P802.3ae specification defines a 10 Gigabit / s Media Independent Interface (XGMII) parallel bus architecture consisting of 74 signals (including two 32-bit data paths, one of which is in the transmit direction , the other in the receive direction; four control signals; and a clock signal). XGMII couples the Ethernet media access control (MAC) layer components (the MAC layer corresponds to the second layer of the International Standards Organization's Open Interconnection System (OSI), that is, the data link layer protocol) to the Ethernet physical (PHY) layer device (PHY layer corresponds to OSI Layer 1, which is part of the physical layer protocol).

[0023] The 10GbE specification also proposes optional XGMII extensions, consisting of two 10 Gigabit Media Independent Interface (XGMII) Extender Sublayers (XGXS) and an XAUI bus between them (“Optional XGMII Extender”; or simply "XGMII Extender") for extending XGMII up to, f...

Abstract

Transmitting data across a scalable, flexible speed, serial bus in a communication protocol independent manner.

Description

technical field [0001] Embodiments of the present invention relate to an apparatus and method for transmitting data in a protocol-independent manner over an IEEE P802.3ae 10 Gigabit Accessory Unit (XAUI) bus. Background technique [0002] A communication bus for coupling between high-performance devices, such as between integrated circuits ("chip-to-chip" communication), between input / output (I / O) devices, or between printed circuit boards via connectors Interconnected communication buses that may need to operate at very high transfer speeds. Also, the interface logic and pin count used to implement the bus may need to be minimized to reduce the cost and complexity of devices within or between the bus. In general, parallel buses cannot meet the needs of many current applications because the data transfer speed of the bus is limited in operation to relatively slow speeds of one billion bits per second, or fewer bits per parallel signal. While simple serial signals are gener...
