Embedded block coding with optimized truncation (EBCOT) is a key algorithm in JPEG 2000 image compression system. In this algorithm, output generated by the bit plane coder (BPC) is supplied to an MQ coder. Though several high speed BPC architectures are available, overall performance EBCOT algorithm is getting restricted by the speed of an MQ coder. Therefore, we propose a high speed, area efficient...
With the growth in multimedia technology, demand for highspeed real time image compression system has also increased. JPEG 2000 standard is developed to cater such application requirements. However, the sequential execution of the bit plane coder (BPC) used in this standard consumes more clock cycles. To improve the performance of the BPC, a new concurrent context modeling technique is proposed in...
In this paper an optimized architecture of bit plane coder for Embedded Block Coding with Optimal Truncation (EBCOT) algorithm targeting its FPGA implementation is proposed. Although several speed up techniques exist, we present architecture whose performance is improved based on detailed analysis of data path used to obtain context windows. Multiplexer based coding style is adapted to utilize the...
