I attended the IEEE 802.3 standards meeting in York, England recently. Over 200 people came from all over the world to work on standards for the next generation of Ethernet products.
Work is ongoing to standardize new Ethernet PHYs (physical layer devices) for speeds of 1Gbps, 40Gbps, 100Gbps and 400Gbps. The 1Gbps work is focused on the automotive and industrial market segments, a field that Cadence is particularly committed to supporting with its Ethernet IP.
Ethernet is expected to be widely adopted in cars -- it meets all the speed, cost, reliability and inter-operability requirements. The IEEE working group is working to standardize a gigabit PHY optimized for automotive environments that will operate over a single twisted pair of copper. This is a speed upgrade to the existing 100M automotive PHY available from Broadcom. There is also consideration being given to start a project to standardize a method of pre-emption to allow time critical traffic to be sent for closed loop control. Pre-emption is something that manufacturers of industrial control systems are asking for, and is also of interest to the automotive market.
