Rotating Video Frame Buffer (RVFB)

The Macnica Rotating Video Frame Buffer is a near drop-in replacement for the Altera Video Frame Buffer available in the “VIP Suite” of functions. In addition to providing a triple-buffer implementation supported frame rate conversion via dropping and repeating of video frames, it provides orthogonal (increments of 90 degrees) rotation and both vertical and horizontal reflection capabilities on a frame-by-frame basis.

Features

  • QSYS-compatible
  • Up to 4K x 4K resolution
  • Efficient memory bandwidth utilization
  • Access to diagnostic and control-related statistics:
    • Number of frames received
    • Number of frames output
    • Number of frames dropped
    • Dimensions of each frame in the buffers
    • Status of each frame (in-use, available)
  • Programmable memory buffer location
  • Control of orientation via Avalon Slave interface on a frame-by-frame basis
  • Parameters allow reduced features for reduced logic utilization
