Abstract
We propose a zero block detection algorithm and architecture in EBCOT. After the detailed analysis of wavelet coefficients’ precision and distribution in JPEG2000, there are three main modes of zero coefficients in the wavelet domain, i.e. zero column, zero stripe and zero code block. And we also discover that the coding information of each bit plane and the corresponding passes can be obtained simultaneously in the hardware structure. Therefore, bit plane-parallel and pass-parallel coding with zero detection is proposed, and its VLSI architecture is shown in details. The analysis and the corresponding software/hardware experimental results show that the proposed architecture reduces the processing time greatly compared with others.
