Multithreaded processing paradigms for JPEG2000

We provide an overview of techniques that are used in a highly efficient software implementation of the JPEG2000 compression standard. We describe a novel multithreaded processing paradigm that achieves near perfect parallel processing scalability, at least over the 8 logical processors for which results are reported. Both thread scalability and overall throughput are shown to be far better than has previously been reported in the literature. For example, we demonstrate realtime processing of 2K and 4K cinema content at 244Mbits/s on a laptop computer. We also demonstrate 9/7 DWT throughputs on a single CPU core with comparable performance to a parallel multi-GPU solution. Finally, we provide results demonstrating the throughput and compression performance of a new “fast mode” that is the subject of an amendment to the standard.
