How it started

History

In 2015, researchers Krste Asanović, Yunsup Lee, and Andrew Waterman from the University of California, Berkeley founded SiFive. On November 29, 2016, SiFive released the Freedom Everywhere 310 SoC and the HiFive development board. This made it the first company to produce a chip that implemented the RISC-V ISA, although some universities had already produced RISC-V processors.

Naveed Sherwani was appointed CEO in August 2017. In October 2017, SiFive did a limited release of its U54-MC, which was reported to be the first RISC-V-based 64-bit quad-core CPU that supported comprehensive operating systems like Linux.

In June 2018, SiFive acquired Open-Silicon for an undisclosed amount and retained its application-specific integrated circuit (ASIC) design capabilities.

In February 2018, SiFive released the HiFive Unleashed, a development board containing a 64-bit SoC with four U54 cores.

In September 2020, Patrick Little was appointed CEO.
