本文详细分析了JPEG-2000中的嵌入式块编码优化截断（EBCOT）算法，并给出了有效的结构设计。通过对EBCOT中语境形成过程的详细剖析，深入了解了EBCOT的操作特点。采用基于列的操作，以实现更高的处理速度。提出了两种加速方法，称为像素跳跃（PS）和列组跳跃（GOCS）。结果表明，超过60%的处理时间可以减少利用这两种方法。一个基于列的架构，使用这些组合的加速思想，然后提出。
This paper presents detailed analysis and efficient architecture design of Embedded Block Coding with Optimized Truncation (EBCOT) for JPEG-2000. Detailed profile of the context formation process in EBCOT is analyzed to get an insight into the characteristics of the operation. Column-based operation is adopted to enable higher process speed. Two speed-up methods, referred to as Pixel Skipping (PS), and Group-Of-Column Skipping (GOCS), are proposed. It is shown that over 60% of processing time can be reduced by exploiting the two methods. A column-based architecture using these combined speed-up ideas is then proposed.
