  • Tested on VisionFive2 boards w/ "Headless" IoT profile. Expanding coverage to "Headed" IoT profile.
  • It will require .NET support to cover general "Consumer Electronics"
  • Samsung will test w/ an actual RISC-V based CE SoC and actual product next year, which will be a test basis for a few RISC-V extensions, too. (23'12: Started.)
  • Mostly working on unpopular open source packages (packages interested by Tizen only, usually components for consumer electronics, or .NET libraries)


Reference Board for Testing

  • 2023: VisionFive2
  • 2024: A new board with a RISC-V chip with more extension supports and various HW IPs.
    • BSP is done. User applications of actual consumer electronics are being tested.
    • Performance evaluation in progress. (doesn't look good at this moment.)

Bringing up a full HW product for testing.

Optimization (AOTC, RVV, General runtime latency) planned (to be compilted in 25')
