    JPEG Encoding acceleration using OpenCL in Image Magick libraries by AMD

    bkmnaidu

      Hi,

       

         I have been looking for a GPU accelerated version of JPEG Encoder (preferably using OpenCL) for AMD Radeon HD 6320 GPU.

      I understand from a video posted here (OpenCL Optimizations on ImageMagick: Convert, Edit, and Compose Images at AFDS 2012 - YouTube),

      AMD has provided OpenCL accelerated functions for JPEG Codecs to Image Magick open source library.

       

      After compiling the library with --enable-opencl flag and installing the binaries, I do not see any improvement in the JPEG compression times and further

      investigation revelaed only convolution of an image is OpenCL-enabled at the moment.

       

      Now, can anyone tell me where I can find the OpenCL-enabled JPEG Codecs for AMD GPU. Alternatively, suggest an  library that has GPU accelerated

      JPEG Codecs support for AMD GPUs.

       

      Your help is very much appreciated.

       

      Regards,
