摘要: JPEG2000 provides excellent compression performance and fine granularity scalability but at the cost of high computational complexity. We propose two speed-up techniques and use the TI DSP optimization tools to accelerate the Tier1 module. We eliminate the unnecessary checking cycles by recording the NBC (Need-to-Be-Coded) samples on a list. Furthermore, the sample index is reordered to facilitate fast execution. In the DSP implementation of the proposed methods, we use code acceleration techniques, cache memory allocation, and TI DSP compiler-level optimization tools. Even when the original program is compiled with the same DSP optimization tools and proper cache assignment, our fast algorithm can still reduce the computation by 45%.
