Demo: LED Cube Using RISC-V®-Based PolarFire® SoC FPGA

on YouTube ↗20m

" summary

Demo reproduces Adafruit’s 6-panel hub75 cube on a BeagleV®-Fire module with a PolarFire SoC FPGA, driving six 64×64 panels (≈24,000 RGB pixels ≈75,000 LEDs) and playing video from Linux. FPGA implements RGB565 conversion, timing, binary coded modulation for brightness and the 384-bit daisy-chained shift registers; RISC-V subsystem runs Ubuntu and a video player using about one core at ~28% while the design uses ≈23% of 23k logic elements and works in real time.
