算术编码作为一种高效的数据编码方法在图像压缩中有广泛的应用。介绍了国际静态图像压缩新标准JPEG2000中的自适应二进制算术编码技术。算术编码的工程实现需要高性能信号处理器的支持，研究了在TMS320VC5402上实现二进制算术编码的快速算法及优化汇编程序金计，证明了其硬件算法的实用性和高效率。该技术可实现对图像压缩编码，在其他数据压缩领域也可以直接利用。

As a kind of data compression technique of high efficiency, arithmetic coding is widely used in image compressing. This paper introduces the adaptive binary arithmetic coding used in the new international standard of still image compression named jpeg2000. The implementation of arithmetic coding depends on high power digital signal processor.Fast adaptive binary arithmetic coding and optimized assembly program design are discussed, and its practicability and efficiency are proved.It also can be used in other fields that need compressing data.
