CUDA JPEG codec for NVIDIA GPUs
We have created fast JPEG codec based on NVIDIA CUDA technology. CUDA JPEG codec developed by Fastvideo is a blend of strict compliance with standards and shocking encoding and decoding speed comparing with existing commercial solutions. This is full, performance-oriented implementation of Baseline JPEG. We got ultra fast JPEG compression and decompression on the GPU due to full parallel implementation of Baseline JPEG algorithm. Our JPEG codec is much more fast in comparison with the best commercial multithreaded JPEG codecs for multicore CPUs.
Fast JPEG image compression features for CUDA JPEG codec
We have succeeded to make parallel all stages of JPEG algorithm including entropy encoding and decoding. There was a widespread opinion that Huffman algorithm could be only serial. In our solution Huffman coding is not a bottleneck anymore and it's fully parallel. Now we don't off-load anything from GPU to CPU to make JPEG codec faster. CUDA JPEG codec is extremely fast and is functioning completely on GPU.
Benchmarks for JPG encoding and decoding on different GPUs
We got the following performance benchmarks for Baseline JPEG encoding and decoding for 24-bit color image with 7216 x 5408 resolution, JPEG quality 75% and subsampling 4:2:0
JPEG encoding results:
JPEG decoding throughput for the same image:
The above results include DeviceIO latency (copy image data from Host to GPU memory and vice versa). We don't include HostIO latency (image loading to Host from HDD/SSD/RAID and vice versa). Fast decompression could be done only for images that were compressed with the same JPEG codec.
Comparison with the fastest IP Cores for JPEG image compression
The idea about online high speed JPEG compression is not new. There are a lot of different JPEG FPGA implementations for that task. Here are several links for the fastest IP cores on FPGA:
We've got much better results with GPU, though we understand that GPU is not a universal solution. We consider GPU to be an excellent choice for many high performance tasks. It could be also interesting if there are no strict limitations on power consumption and dimensions.
Options for CUDA JPEG image compressor
We can offer custom software design for combined debayer and JPEG compressor on NVIDIA GPU and other solutions:
We can also extend our JPEG compression software by fast image processing pipeline for high speed and high resolution cameras: bad pixel removal, dark frame subtraction, shading correction, white balance, demosaicing, image filtering, gamma, LUT, color management, online resize, OpenGL output, etc.
