Minimized Area and High Speed EBCOT Architecture for JPEG 2000
摘要
In this study we have proposed minimized area and high speed EBCOT architecture for JPEG 2000. Embedded block coding with optimized truncation is an algorithm in JPEG 2000 image compression system. In several existing high speed EBCOT architecture is there in our proposed it overcomes and produce code generation. In our study open that image rate of more context dual generation is about 74.8%. To encoding the all image samples in a column, a new formulated named as pact context coding is invented as a important, high devised is used for less hardware. The proposed architecture is described in VHDL language, verified by simulation and successfully implemented in a Cyclone II and Stratix III FPGA. It provides a major reduction in memory access requirements, as well as a net increase of the processing speed as shown by the simulations. The C*D Quantizer coder is improved by the operating system and stage. The full design of processor encoder is tested on FPGA based. The results show that invented of the proposed architecture 172.28 M samples/sec is equaling to encode 1920*1080 (4:3:3) HD camera picture sequence at 39 f/sec. the bit plane architecture operates 315.06 MHZ which that implies that it is 4.03 times faster than the but plan coder so far. It is used many applications like satellite image, medical image and image compression system.
