Shortest Blog Post Ever…

…at least for Richard 🙂

Posted in PCI Express

Flashback to Basics Friday! What’s in a name…

“What’s in a name? that which we call a rose by any other word would smell as sweet” How many times do you get Shakespeare in a tech blog? Well, here at ExpressYourself we like to cover all the bases 🙂 (I’m fond of announcing that “I have a poetic license and I’m not afraid to use it!” much to the chagrin of my children I’m sure.)

1, 2, 3, 4, 5… It’s Official, PCIe 5.0 is Announced

At the PCI-SIG DevCon in June 2017 two announcements were made with regards to PCI Express specifications. The first is that the specification for PCIe 4.0 is now at version 0.9. The second and even more interesting announcement was of the new PCI Express 5.0 specification at the initial 0.3 version. With the PCI Express 5.0 announcement, the industry gets another doubling of speed from 16.0GT/s to 32GT/s per lane providing a bandwidth for a x16 (16 lanes) at about 128GB/s. The chart below provides a comparison for the different generations of PCIe rates and bandwidth.

PCIe 4.0 Ecosystem with Synopsys and Mellanox

Synopsys has a long history of working with ecosystem partners as part of the development process, especially when new versions of a specification are rolled out. The PCIe 4.0 specification has taken a long time, but that hasn’t slowed us down. If you remember from previous postings, some of our PCIe 4.0 demos include:

Proper Preparation Prevents Poor PCIe Performance

Ok, so maybe that’s not the 6P’s (or 5P’s or 7P’s depending on where you first learned it) most folks may be familiar with, but it seemed pretty proper for a performance posting…plus someone said Solomon is a serious sucker for alliterations! (Hey, now that I can no longer make IDF jokes, you just KNEW I was going to have to find another outlet!)

Beware the Ides of March!

About

This blog is all about PCI Express: the wonderful ways that it enhances the products around you, the challenges designers face in implementation, and how the specification is evolving to make PCIe Express an even more useful protocol. I'll also examine how the other specifications, such as NVM Express, SATA Express and SCSI-Over-PCI Express (SOP) are leveraging PCI Express. If there is a topic that is of interest to you, feel free to "Express Yourself" by offering your insights on this blog.

About the Author

Scott Knowlton
I started out my career as a chip designer in a variety of industries and it’s likely that a few, of the more than 30 designs I’ve been responsible for, are still floating around somewhere in outer space. My IP career started at Synopsys in 1997 and over the last 15 years, I have seen tremendous changes in the semiconductor industry’s perception and adoption of IP. I started working on PCI Express in 2003 when Synopsys was getting ready to launch our first PCI Express IP solution. Since then, I have been managing the DesignWare PCI Express IP product line through all of the changes in the specification and the industry as it moves towards becoming the de-facto interconnect standard. I received a B.S.E.E from the University of Michigan (M Go Blue!), am an avid red wine drinker (love California reds) and use English as a second language when my fluency in sarcasm just doesn’t get the job done.

I’ve been involved in the development of PCI chips dating back to the NCR 53C810 and pre-1.0 versions of the PCI spec so have definitely lived the evolution of PCI Express and PCI since the very beginning! Over the years I have worked on variations of PCI, eventually moving on to architecting and leading the development of the PCI Express and PCI-X interface cores used in LSI’s line of storage RAID controller chips. For the last ten plus years I've also had the honor of serving on the PCI-SIG Board of Directors and holding a variety of officer positions. I am still involved in PCI-SIG workgroups and I present at many PCI-SIG events around the world. Back before the dawn of PCI, I received my B.S.E.E. from Rice University, and hold over two dozen U.S. Patents, many of which relate to PCI technology.
