7th RISC-V Workshop Proceedings

November 28, 2017
|By Holly Stump

Our goals for these events are to bring the RISC-V community together to share information about recent activity in the various RISC-V projects underway around the globe, and build consensus on the future evolution of the instruction set.

  • Tuesday and Wednesday November 28-29, 2017 – These two days followed our traditional two day format used at previous workshops with presentations covering various RISC-V projects underway within the RISC-V community and will include a poster / demo reception on Tuesday evening.
  • Thursday November 30, 2017 – The workshop week concluded with RISC-V Foundation meetings with attendance restricted to members of the RISC-V Foundation.  The day consisted of Technical and Marketing Committee face to face meetings to progress the work currently underway within our various Task Groups.

Each workshop has helped both document the rapidly rising popularity of RISC-V and boosted it further due to the information shared and collaborations formed at the event.
