Ringing in 2018 with fresh faces and big resolutions
Before we dive into our newsletter, we want to take a moment to talk about the vulnerabilities around Meltdown and Spectre. First off -- and most fortunately -- SiFive’s RISC-V Core IP offerings are not affected by Meltdown and Spectre. Secondly, as the RISC-V Foundation’s statement on these vulnerabilities notes, now is the time for open architecture and open hardware designs to shine.

Now, on to the fun stuff.

We wrapped up our “Getting Started with SiFive IP” webinar series last week. The three-part series covered everything from instruction types and modes to using evaluation versions of our E31 and E51 Core IPs. Missed a webinar? No sweat -- we have you covered. Check out the recordings to all three sessions here. 

Last, but certainly not least, we were fortunate enough to welcome Sunil Shenoy, former corporate VP at Intel, to the growing SiFive team as vice president of hardware engineering. Sunil brings more than 30 years of technology experience to SiFive, from holding 16 patents in microprocessor design to leading multi-national teams of thousands of engineers. We’re thrilled to have him on board and expanding our mission to simplify access to customizable RISC-V Core IP!

All Aboard: An Update on RISC-V

Since the Workshop, Palmer’s been furiously covering the RISC-V ecosystem. Here are some of his recent thoughts:

Are you interested in being a part of the evolution? Let’s talk!

Upcoming Events

We’re headed to Brussels for the upcoming FOSDEM 2018 event! Our very own Palmer Dabbelt will be speaking on Saturday, Feb. 3. His panel, titled “Igniting the Open Hardware Ecosystem with RISC-V,” will explore the RISC-V ISA, the Rocket Chip processor generator and the state of RISC-V.

Embedded World is also coming up in Nuremberg, and we’ve teamed up with the RISC-V Foundation to sponsor a “passport” program where attendees can visit multiple RISC-V member companies at the show and have a chance to win a HiFive1 board.


Featured Developer

Our view of the world centers around the developer, the engineer, the user, the dreamer. It’s you who are contributing to RISC-V and open-source, making what we would do at SiFive possible.


This month’s featured developer is Stephen Newberry. Stephen is a hardware engineer who is passionate about PCB design and VHDL. Pursuing his curiosity around RISC-V and programmable logic, Stephen began working on a board based on the SiFive FE310 and a Xilinx Artix-7 FPGA. Named fRISCy (for FPGA + RISC-V), he hopes the board would be suitable for development and inclusion in industrial embedded systems. We are eagerly following Stephen’s progress on the fRISCy via the SiFive forums and will be excited to see the prototype.

Some of fRISCy’s key features include:

  • SiFive FE310 RISC-V Microcontroller (system controller) with 128Mbit QSPI Flash memory
  • Xilinx Artix-7 FPGA with SYZYGY Standard carrier-side connector (footprint compatible from XC7A15T to XC7A100T)
  • Raspberry Pi form factor and connector placement, including 40-pin GPIO header, RJ-45, and USB Micro-B
  • 10/100 Ethernet PHY and 4Mbit SRAM connected via FPGA
  • SPI + GPIO interface between FE310 and FPGA for bidirectional data transfer
  • FDTI and UART interfaces

We’d love to feature your SiFive project in the next newsletter - let us know what you are working on!


Forum Highlights
The SiFive Forums are buzzing! They are packed with valuable content that can answer your questions and curiosity surrounding RISC-V, development boards, IP evaluations and much more. Here’s a peek at some of the threads that caught our attention (and will now have yours, too!):
