Enhanced Video Post Processing (eVPP)

Product Details

The Enhanced Video Post Processor has the capabilities of downscaling and up scaling of images of different input and output sizes. The input and output sizes are limited by the L3 memory. eVpp supports YUV420 input for interlaced and progressive inputs for images of size less than 480p and progressive input for sizes greater than 480p. Output picture formats supported include YUV2-422, YUV422, CCIR PAL/NTSC, RGB888, RGB565 and BGR565 for progressive and interlaced outputs. Blending is handled for all downscaling cases. Blend image can be specified in runtime.

Features

  • Picture input format (downscaler): Interlaced and progressive inputs for images of size less than 480p and progressive inputs for sizes greater than 480p. Input width is expected to be a multiple of 16. YUV420 is the input type
  • Picture input format (upscaler): Progressive inputs for images of all size for YUV420 input type
  • Picture output format (upscaler): Progressive with output type of YUY2-422
  • Picture sizes: All progressive picture dimensions up to and larger than 10MP on the input are supported. The output size may be arbitrary, but is currently validated for up to 800x600 for YUV422 output and 720x480 for rgb888 output
  • Blending: Supported for all downscaling cases. The blend image can be specified in run time
  • API: C callable API
  • Compliance: ADI internal Quality assessment
  • Code base origin: Based on ADI propriety design Reference Code Revision #: NA
  • Certification: NA
  • Release Format: Object Code with source code wrapper
  • Target Processors: BF533, BF527, BF561 and BF548
  • Multi-instancing: Fully re-entrant and multi-instancing capable

Performance Metrics

 MIPS summary:

Code memory (KB) Data RAM (KB) Constant Data Tables (KB) MIPS Average
20 33* 311 160

*This is exclusive of the input and output image buffers. Input Buffer size in Bytes is InputWidth x InputHeight x 1.5. Output Buffer size for YUV422/RGB565/BGR565 is Output Height x Output Width x 2, for RGB888, the size is Output Height*Output Width*3. Table size indicated is for very large downscale for 10MP images. For sub-D1 images the table sizes would be much smaller. Case considered here is for a 320x240 input and output of size 720x480 in YUV422.

  • For MIPS measurement, Data cache (writeback is enabled in a 32KB cache configuration. Data caching is used for coefficients).
  • DMA is enabled for data.
  • Instruction cache is disabled.
