• Back to back filter2D with batch size three support

  Application showcasing increasing throughput of single filter2D kernel, by doing 3, back-2-back filter2D achieving 555 FPS with PL datamovers.

New Programmable Logic (PL) functions and features:

• ISP pipeline and functions:

  • End to End Mono Image Processing (ISP) pipeline with CLAHE TMO

    Useful for ISP pipelines with monochrome sensors

  • RGB-IR along-with RGB-IR Image Processing (ISP) pipeline

    Useful for ISP pipelines with IR sensors

  • Global Tone Mapping (GTM) along with an ISP pipeline using GTM

    Adding to growing TMO (tone-mapping-operators) in the library for different quality and area tradeoff purposes: CLAHE, Local Tone Mapping, Quantization and Dithering

Known issues

• Vitis GUI projects on RHEL83 and CEntOS82 may fail because of a lib conflict in the LD_LIBRARY_PATH setting. User needs to remove ${env_var:LD_LIBRARY_PATH} from the project environment settings for the function to build successfully.
