VGA/SVGA Display Controller Core

VGA/SVGA Display Controller Core



  • Generates color and control data for standard VGA/SVGA displays
  • Works in conjunction with external video DAC such as Analog Devices’ ADV7120
  • Supports resolution up to 1024 x 1024 (higher resolutions available upon request)
  • Accepts two standard video data formats:
  • 24-bit RBG (8:8:8)
  • 15-bit RBG (5:5:5)
  • Outputs standard 8:8:8 24-bit RGB video (converts from 5:5:5 if necessary)
  • Display functions with hardware support:
  • Scroll (in horizontal and vertical directions)
  • Sub-screen display (any position)
  • Horizontal flip screen
  • Fully configurable monitor frequencies and aspect ratios
  • 32-bit data path
  • Configurable internal FIFO
  • Integrated Test mode: core generates color bar without any AHB bus transactions
  • Internal, event-stimulated, interrupt request generation with masking capability
  • Dedicated unidirectional DMA controller with burst transaction support
  • Built-in Power Save mode
  • Requires an external pixel clock.
  • Integrated with AMBA™ bus:
  • AMBA™ AHB slave unit interfaces with host controller
  • AMBA™ AHB master unit interfaces with host memory
