Right now, the most prevalent generation of Ethernet for data centers is 400 Gbps, with the shift to 800 Gbps coming rapidly. It is expected that by 2025 there will be 25 million units of 800 Gbps shipped. Line speeds of 100G are used predominantly for 400 Gbps Ethernet – requiring 4 lanes each. Initially 800 Gbps will simply … Read More
Cars are hotbeds of systems innovation. I’ve been fortunate to be asked to write about many of these areas, from the MEMS underlying sensors to ISPs and radars, intelligent imaging and sensor fusion. And many aspects of design for safety within the SoCs around a car. But I haven’t written much about the networks connecting these … Read More
If I ask the question, “What has grown 4,000x over the last twenty-five years?”, most people will start throwing names of some stocks. Although various stock markets have had crazy run ups and yes, there is a stock that has grown 2,500x over that period of time, the answer to the 4,000x question is not a stock. What if I modify the question… Read More
Back in May I wrote an article on the new Speedster7t from Achronix. This chip brings together Network on Chip (NoC) interconnect, high speed Ethernet and memory connections, and processing elements optimized for AI/ML. Speedster7t is a very exciting new FPGA that can be used effectively to accelerate a wide range of processing… Read More
Up until 2016, provisioning Ethernet networks was a little bit like buying hot dogs and hot dog buns, in that you could not always match up the quantities to get the most efficient configuration. That dramatically changed when the specification for Ethernet FlexE was adopted by the Optical Internetworking Forum as OIF-FLEXE-01.0.… Read More
From my restaurant seat today in Lake Oswego, Oregon I watched as an SUV driver backed out and nearly collided with a parked car, so I wanted to wave my arms or start shouting to the driver to warn them about the collision. Cases like this are a daily occurrence to those of us who drive or watch other drivers on the road, so the promises of… Read More
Due to the overwhelming response, here is the first part of the webinar that I did with S2C and a link to the replay. Richard Chang, Vice President of Engineering at S2C did the technical part of the webinar. Richard has a Masters degree in Electrical engineering from the University at Buffalo and more than 20 years experience designing… Read More
The data center rack server market is estimated to growat a high Compound Annual Growth Rate (CAGR) of 20% to reach $90 billion by 2021. Such growth is due to the significantly rise in the number of connected devices, the growth in the volume of data per device and theneed for quick processing of high-volume data. Much of these data … Read More
Once upon a time the role of electricity in a car was pretty modest: spark plugs, alternator, lighting, some simple instrumentation and maybe heating, all supported by an equally simple wiring harness (my wife has a 1962 Morris Minor, so I know exactly what the whole wiring harness looks like). How times have changed. Now most or … Read More
IPnest is launching the “Interface IP Survey” since 2009, and we did it last September again. To build the survey as accurately as possible, I have followed the “divide and conquer” strategy. Interface protocols are varied, ranging from PCI Express, USB, or Ethernet, to memory controller (DDR3, DDR4, LPDDR3, LPDDR4 and more) … Read More
