MCIMX27VOP4 Datasheet, PDF (14/118 Pages) Freescale Semiconductor, Inc – Multimedia Applications Processor

Functional Description and Application Information
– System memory
– Private DMA between CMOS Sensor Interface module and pre-processor
— Data input formats:
– Arbitrarily formatted RGB pixels (16 or 32 bits)
– YUV 4:2:2 (Pixel interleaved)
– YUV 4:2:0 (IYUV, YV12)
— Input image size: 32 × 32 to 2044 × 2044
— Image scaling:
– Programmable independent CH-1 and CH-2 resizer. Can program to be in cascade or
parallel.
– Each resizer supports downscaling ratios from 1:1 to 8:1 in fractional steps.
— Channel-1 output data format
– Channel 1
– RGB 16 and 32 bpp
– YUV 4:2:2 (YUYV, YVYU, UYVY, VYUY)
— Channel-2 output data format
– YUV 4:2:2 (YUYV)
– YUV 4:4:4
– YUV 4:2:0 (IYUV, YV12)
– RGB data and YUV data format can be generated concurrently
— 32/64-bit AHB bus
• Post-processor
— Input data:
– From system memory
— Input format:
– YUV 4:2:0 (IYUV, YV12)
— Image Size: 32 × 32 to 2044 × 2044
— Output format:
– YUV 4:2:2 (YUYV)
– RGB16 and RGB32 bpp
— Image Resize
– Upscaling ratios ranging from 1:1 to 1:4 in fractional steps
– Downscaling ratios ranging from 1:1 to 2:1 in fractional steps and a fixed 4:1
– Ratios provide scaling between QCIF, CIF, QVGA (320 × 240, 240 × 320)
