Hardware Implementation of Tag Tree in JPEG2000 Encoder

Hierarchical data structure takes an importance rule in many files such as computer graphic, information storage and retrieval, image processing etc. Quad-tree is a kind of hierarchical data structure which is applied widely in image coding. Tag tree, a particular type of quad-tree, is a coding mechanism used in tier-2 coding engine in JPEG2000 encode. In this paper, we propose a hardware implementation of tag tree in JPEG2000 encode system. Tag tree is successful implemented on hardware system, tested by using OpenJPEG and simulated on
Modelsim and VCS tools.
