Single-loop architecture for JPEG 2000

Abstract

We present a novel and very efficient software architecture designed for JPEG 2000 coders. The proposed method employs a strip-based data processing technique while performing a single-pass multiscale wavelet transform. The overall compression chain is driven by incoming data while the fragments of the resulting bitstream are produced immediately after loading the corresponding data and additionally in parallel. The method is friendly to the CPU cache and nicely exploits the SIMD capabilities of the modern CPUs. Implanted into reference OpenJPEG implementation, our method has significantly better performance in terms of the execution time.
