Project Peacock will be (in theory) a chipset for doing DVI/VGA display output from a microcontroller. It will consist of:

  • Display Driver CPLD
  • Display Controller MCU
  • RAM
    • SRAM
      • Far too expensive (~$200) for the amount needed
    • PSRAM (Pseudo SRAM)/CellularRAM
      • SRAM interface but DRAM backend, simple to interface with and cheap (~$6)
      • Only available in VFBGA package meaning a four-layer board would be required, and hard to solder
    • SDRAM
      • Inexpensive (~$5) and readily available
      • Easy non-BGA SMT packages
      • Harder to interface with, would need to have the CPLD handle RAM refreshing and other housekeeping
  • Output converter
    • TMDS converter for DVI
    • DAC for VGA
