This core is part of the Milkymist System-on-Chip, the most advanced open source SoC for interactive multimedia applications.

  • Minimal VGA framebuffer core
  • RGB565 16bpp
  • Directly drives a 3x8-bit DAC and sync signals.
  • Fully configurable timings and resolution
  • Multiple buffering support with buffer switch during the blanking interval to prevent tearing artifacts.
  • Milkymist CSR and FML bus interfaces.
  • Two asynchronous clock domains - VGA and system.
  • Bit-banged DDC interface.
