The New Spec Draft’s Here, The New Spec Draft’s Here!

Ok, so the title reference might be a bit aged for many of our readers… You young-uns can check out this YouTube video for a hint.  On the offhand chance that you missed the email from PCI-SIG, I’ll give a (PCI-SIG members-only of course) link directly in to the new 0.7 Draft of PCI Express 4.0: https://members.pcisig.com/wg/PCI-SIG/document/download/9977

Real Reality

Scott and I are out at IDF (Intel Developer Forum – not the Tavor-wielding IDF) this week, where the keynote yesterday was all about Virtual Reality, Augmented Reality, and Merged Reality …. oddly not much was said about plain old real reality.  If you missed us last week at Flash Memory Summit (FMS) please stop by Booth #230 and say “Hi”.  Heck, even if you didn’t miss us, come by anyway!  Speaking of FMS, I should first give you an…. FMS AAR (After Action Report) I apologize for not posting sooner, but after spending so much time last week chanting under my breath my favorite old Polish folk-saying (“Not my circus, not my monkeys!”) I was struggling with exactly what to post about FMS.  Suffice it to say that there were a number of logistical “challenges” with the show itself – culminating in a no-show of the moderator for the PCIe/NVMe session.  However, I did have a good turnout of 50-60 folks for my session on using PCIe 4.0 in SSDs.  I really appreciated everyone’s patience as the speakers worked out our own lineup and introductions (and no, for the record, despite how I introduced him, Debendra didn’t *actually* invent a banana peeler).  There was definitely a lot of interest in PCIe 4.0 from SSD folks and that was evident in our booth traffic as well.  This shouldn’t be surprising to anyone given new technologies in non-volatile media and the relative ease of aggregating NAND (or other) chips to get extremely high bandwidth, not to mention that most common PCIe SSD form-factors are limited to 4 lanes.  (Remember that SFF-8639, now sometimes called U.2, and the newish M.2 form-factor both top out at PCIe x4 configurations so their only real choice for more bandwidth is higher signaling speed.)  Regardless of the hiccups, thanks for all those who stopped by – including some old friends and colleagues:

Beer, Pizza, and PCI Express Pontification

Sorry this is so last-minute, but any of you who are at Flash Memory Summit this week, please stop by Tuesday night for “Beer, Pizza and Chat with the Experts” (7pm-8:30pm) where I’ll have a table on SSD Interfaces.  Of course this will be completely neutral 😀

Come run with the big dogs at PCI-SIG Devcon 2016!

Hopefully all of you have made plans to attend this year’s PCI-SIG Developers Conference (aka Devcon) next week in Santa Clara.  This is THE event to learn about PCI Express technology, and network with your fellow PCIe ecosystem members.  Of course Synopsys will be there, both on the exhibition hall floor and in the Member Implementation tracks.  Come listen to the big dogs from Synopsys R&D teach you (and our competitors) about two important topics.  First, come by Track 3 on Tuesday at  3:30pm to hear how we got our DesignWare Root Port IP for PCI Express on the PCI-SIG Integrator’s List as the first *EVER* from an IP provider!  Don’t miss the 10:30am Wednesday morning session (also in Track 3) on PCI Express in automotive applications.  Yes, it’s true, I’m taking a bit of a rest on this one and “only” presenting PCI-SIG sessions this time, but the other Synopsys presenters will keep you informed, even if they’re not as funny as I think I am 😀

Ordering by the Numbers … and SNUG China

Full disclosure: this is NOT a posting about PCI Express ordering rules, though that’s a great topic which I’ll use for a future posting.

Flashback to Basics Friday! Bandwidth…

I’ve been thinking for a while (yes, that explains the burning smell) that we should be covering some of the basics of PCI Express here at ExpressYourself in addition to “just” the new stuff.  After reading today’s posting, please let me know in the comments whether this is a good idea or not…

Silence, SNUG, and Specification Status

“What’s this?!?!?  A blog posting from Richard?  Wasn’t he killed in a fiery camel-riding crash at the last PCI-SIG Israel event or something?”

The Long Lost Video: The World’s 2nd PCIe Gen4 System

The video at ARM TechCon of our 2nd PCIe Gen4 system got kind of lost in our end of the year, Thanksgiving, Christmas, New Years, End of the 1st Quarter rush. I know that my videos of PCIe won’t win any Oscars, but one wonders if someone is just hiding this masterpiece from the public eye. Ok, ok, it’s not a masterpiece, but I’m sure folks would like to see PCIe 4.0 in action. Just for fun, see if you can find my mistakes! There are at least 5!
