EBCOT (Embedded Block Coding with Optimized Truncation) is the core coding algorithm for lossless and lossy compression in JPEG2000 and its complexity lies mainly in the data rearrangement and bit-plane coding. For large-scale image compression processing, EBCOT algorithm has high computational complexity and storage overhead and requires efficient parallel structures for implementation.This paper mainly studies the EBCOT coding algorithm in JPEG2000 and proposes an efficient parallel implementation scheme based on FPGA technology. Specific implementation includes hardware design of key algorithms such as data rearrangement, bit-plane coding, and reorganization of compressed data streams. Finally, the correctness and effectiveness of the design scheme are verified through experiments, and the performance and feasibility of the proposed scheme are fully evaluated.精品文档---下载后可任意编辑Keywords: JPEG 2000, EBCOT coding, parallel structure, FPGA implementation
