The LeapFrog Diji

Discussion


Graphics hardware

  • Resolution: 320x240
  • Display Modes: RGBA 565
  • MLC: Multi-layer controller provides HW compositing for up to three graphics layers
    • One 24-bit 2D layers (no HW accel)
    • One 16-bit 3D layer
    • One YUV video layer (no HW accel)
  • Graphics API OpenGL ES 1.1: A reduced instruction set version of OpenGL for embedded systems. OpenGL is a 3D graphics programming interface. Proprietary interface to Multi- Layer Display controller for 2D RGB and YUV video buffer support. FreeType Font renderer. Theora video codec plays OGG-Theora files.
