Esperanto Presents at the RISC-V Summit 2022

Hear Dave Ditzel of Esperanto Technologies speak at the RISC-V Summit 2022

Dave Ditzel, Founder and CTO of Esperanto Technologies, will deliver a presentation, “Real World Results using Thousands of RISC-V Cores for AI and Beyond,” at the RISC-V Summit on December 13, 2022.

The RISC-V community – including the technical, industry, domain and special interest groups who define the architecture’s specifications – attend the RISC-V Summit for four days of technology breakthroughs, industry milestones, tutorials, and relationship building. The event runs December 13–14, 2022 in San Jose, CA.

Presentation Title: Real World Results using Thousands of RISC-V Cores for AI and Beyond
Speaker: Dave Ditzel, CTO and Founder, Esperanto Technologies, Inc.
When: Tuesday December 13, 2022 4:45pm - 5:05pm PST
Where: Grand Ballroom A, San Jose McEnery Convention Center, 150 W San Carlos Street, San Jose, CA 95113
Abstract: Esperanto’s ET-SoC-1 features over a thousand 64-bit RISC-V vector/tensor cores on a single 7nm chip. This product started shipping to customers in 2022. This presentation will discuss the architecture of the ET-SoC-1 and how it is incorporated into systems appropriate for data centers. This presentation will present real world results in both performance and performance per watt. We will show a system example where a single rack could hold over 300,000 RISC-V processors. The results demonstrate that one can achieve excellent results for accelerating machine learning and other applications by building on top of the general-purpose RISC-V instruction set. One does not have to resort to GPUs to get good performance per watt, RISC-V is a better alternative. This talk will also discuss Esperanto’s roadmap, which will incorporate chiplet inter-operability and much higher performance, improved performance per watt, and larger number of cores per package.
Track: Industry, High-Performance Computing & Data Centers

Esperanto Delivers Keynote at MICRO 2022

Hear Dave Ditzel of Esperanto Technologies at MICRO 2022

Dave Ditzel, Founder and CTO of Esperanto Technologies, will deliver a keynote, “The RISC journey from one to a million processors,” at MICRO on Oct 3.

MICRO 2022 is the 55th IEEE/ACM International Symposium on Microarchitecture®.
The event runs October 1–5, 2022 in Chicago, Illinois.

Keynote: “The evolution of processor design in the last 50 years has taken a variety of paths, but the principles embodied in RISC design have been one of the most used approaches over the last 25 years. This talk will make the case that general-purpose RISC processors are likely to stay in the mainstream for the foreseeable future, along with other key technology developments that will influence the design of processors of the future. Having been an active participant in the RISC revolution since the term was coined in 1980, this talk will review some of the salient achievements in the evolution of RISC until today, and talk about where the future will lead us. Most notable is that until recently, much computing has been done on only a single or small number of processor cores, but that we are entering a renaissance where access to thousands to millions of processor cores will be as common as a desktop computer is today. This talk will touch on some of the key technology advances that will enable our RISC based future and make some predictions for what we can expect in the next decade.” – Dave Ditzel

Esperanto in EE Times Silicon 100

Esperanto Technologies is featured in the EE Times Silicon 100: “Startups to Follow in 2022.
By Peter Clarke:

  • “The Silicon 100 is the “who’s who and who’s doing what” in the global electronics and semiconductor industries.
  • The EE Times Silicon 100, now in its 22nd edition, is not just a list of electronics and semiconductor startups to watch. It explores the non-linear relationship between capital investment and technological innovation and draws a nuanced picture of the changing dynamics and trends in the global startup ecosystem.
  • Peter Clarke, a veteran technology and business journalist who has compiled and curated the EE Times Silicon 100 list since its inception in 2004, has ranked the most promising startups in a weighted selection of fresh-faced youngsters, familiar faces, and fast growers.”
