on YouTube ↗17m

" summary

A 64-bit RISC‑V Linux dev board ships a FU540 SoC with four U54 application cores plus one E51 core running at 1.5 GHz, a 2 MB banked L2, and 8 GB DDR4 on the HiFive Unleashed board, priced at $999 in the initial run and early access sold out with 25 FPGA expansion bundles (one sold). It boots Debian, runs a browser and Google Maps, and streams a webcam frame across FMC + FPGA expansion to an ATS inference accelerator that returns bounding boxes; full board power is ~2–3 W.
