The third of three events taking place in the first three weeks of December is the RISC-V Summit. The RISC-V Summit takes place from December 8 to 10. You can read my preview posts about the other two December events from earlier in the week:

• Cadence 5th Annual Photonics Event
• IEDM 2020 Preview
  

Of course, the RISC-V Summit is virtual.

Let me give you a one-paragraph summary on what RISC-V is. It is an instruction set architecture that is open, in the sense that anyone can use it without cost (or royalties). It is not an open-source core (although those do exist), it is not a proprietary core (although those do exist). This is a slide from Krste Asanovic from the recent RISC-V Global Forum that shows what is available from whom (not a complete list):

There were also several presentations at the recent Linley Processor Conference about RISC-V, which gives at least one datapoint on how much traction the ISA is getting from the industry:

• Graphics, Compute & AI Extensions Based on the RISC-V ISA by Think Silicon (Applied Materials)
• Extending AI SoC Design Possibilities Through Linux-Capable Vector Processors by SiFive (Krste himself)
• A RISC-V OOO Vector Processor by Andes Technology
• Creating a RISC-V PC Ecosystem for Linux Application Development by SiFive (Yunsup)

Tuesday 8

Note that this is not the entire agenda, this is just some of the presentations that I consider especially noteworthy since I've seen presentations at prior RISC-V Workshops/Summits.

Opening keynote by Calista Redmond, CEO of RISC-V International, 9:00am to 9:15am: RISC-V Unconstrained Growth and Opportunity. RISC-V International, now based in Switzerland, is the umbrella organization that "owns" the RISC-V name. Cadence is a member.

Keynote by Siva Sivaram of Western Digital, 9:15am to 9:30am: RISC-V for Next-Generation Storage and Compute. Western Digital is probably the company most committed to RISC-V. They have said that all the cores that they ship (billions in flash controllers) will be moved to RISC-V. They have designed their own core already, called SweRV and open-sourced it. You can read more in my post RISC-V Cores: SweRV and ET-Maxion.

Presentation by John Morris of Seagate, 9:30am to 9:45am: RISC-V Accelerating Innovation in Data Storage. I don't know how strategic RISC-V is to Seagate. Perhaps John will tell us in this presentation.

Keynote by unnamed presenters, probably Krste and/or Yunsup of SiFive from 9:45am to 10:00am: No title yet.

From 10:00am to 10:30am, there will be a live Q&A wit the keynote speakers.

Presentation by Tim Ansell of Google from 12:30pm to 12:50pm that is not (directly) to do with RISC-V but with open-source hardware in general: Fully Open Source Manufacturable PDK for a 130nm Process. You can read more about that in my post Open Source Hardware.

Presentation by Krste Asanovic of UC Berkeley and SiFive from 2:00pm to 2:30pm: RISC-V Vector Extensions for Scaling Intelligence to the Edge. Krste is the "father" of RISC-V and has been one of the main drivers of the vector extension.

Presentation by Art Swift CEO of Esperanto Technologies from 2:30pm to 2:50pm: Esperanto Accelerates Machine Learning With RISC-V. Esperanto has designed what I think is the most advanced RISC-V implementation, a super-scalar out-of-order core called ET-Maxion and a companion ET-Minion designed for ML. You can read more in my post RISC-V Cores: SweRV and ET-Maxion.

Wednesday 9

Keynote from 9:00am to 9:15am by Krste Asanovic with his "chairman of the board of RISC-V International".

There are a couple more keynotes not yet announced.

10:00am to 10:30am: A fireside chat with Dave Patterson, the inventor of RISC (as in RISC-I), co-author of the standard book on computer architecture, and a contributor to RISC-V, too. I covered another fireside chat with him at SEMICON West in my post Dave Patterson on Becoming a Computer Scientist...and Going Directly to Happiness.

10:30am to 11:00am: A live Q&A with the keynote speakers.

11:00am to 11:20am: A presentation of my old colleague from Ambit, Simon Davidman (who also ran CoDesign that developed Superlog that became SystemVerilog), RISC-V and SoC Architectural Exploration for AI and ML Accelerators.

2:30pm to 2:50pm: Another presentation on open hardware design not directly RISC-V related by Mohamed Kasem and Mohamed Shalem, A Complete No-Human-in-the-Loop Open-Source "Idea to Manufacturing" SoC Compiler. The flow goes from JSON to GDSII.

Thursday 10

12:00pm to 1:00pm (note that this presentation is an hour compared to most which are 15 or 20 minutes): A Guide to the RISC-V Cryptography Extension. The two presenters are Ben Marshall of University of Bristol and Barry Spinney of NVIDIA. NVIDIA was one of the first chip manufacturers to use RISC-V when they decided to replace the administrative processor on their GPU (which was previously a proprietary design) with a RISC-V core.

Note that there are lots of other presentations. I picked these ones out since I know who the presenters or the companies are from previous RISC-V Workshops/Summits.
