SD video.8Local storage of complex scatter-gather tables for DMA engine
(eliminates read overhead)
Video Processing Polyphase FIR scaling engine (7x5) for hardware downscaling and
upscaling
Colour space conversion allows captured data to be transferred in any
format:
• RGB 16 bit (5-5-5, 5-6-5), 24 bit (8-8-8) or 32 bit (8-8-8-alpha)

• Mono: 8bit
DMA Engine Direct DMA to physical or virtual memory buffers with full scatter-gather
support.
DMA bandwidth : 800MB/s
16 independent DMA streams:
• Any mix of HD and SD sources, colour space, cropping and scaling
parameters
