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.

The recently disclosed speculation-based timing attacks Meltdown and Spectre have received much attention this week—and rightly so. The vulnerabilities these attacks exploit are not limited to a particular instruction-set architecture, nor are they restricted to a single vendor’s implementations. Many processors that rely upon speculation to improve performance are affected, even some that do not use out-of-order execution.

A new year brings new opportunities. Before we dive into 2018, we wanted to take some time to reflect on some of the excitement we experienced over the last couple of months.
