Detailed profile of the context formation process in EBCOT is analyzed to get an insight into the characteristics of the operation. Column-based operation is adopted to enable higher process speed. Two speed-up methods, referred to as Pixel Skipping (PS), and Group-Of-Column Skipping (GOCS), are proposed. It is shown that over 60% of processing time can be reduced by exploiting the two methods. A column-based architecture using these combined speed-up ideas is then proposed. 10 7.56

Analysis and architecture design of block-coding engine for EBCOT in JPEG 2000
Embedded block coding with optimized truncation (EBCOT) is the most important technology in the latest image-coding standard, JPEG 2000. The hardware design of the block-coding engine in EBCOT is critical because the operations are bit-level processing and occupy more than half of the computation time of the whole compression process. A general purpose processor (GPP) is, therefore, very ineffi...
متن کاملAnalysis and VLSI High Speed of Parallel Causal EBCOT Architecture for Image Compression
Embedded block coding with optimized truncation (EBCOT) is a key algorithm in digital cinema (DC) distribution system. Though several high speed EBCOT architectures exist, all are not capable of meeting the DC specifications. With the augmentation in multimedia technology, demand for high speed real time image compression system has also increased. JPEG2000 is a relatively new image compression...
متن کاملEBCOT coprocessing architecture for JPEG2000
JPEG2000 is the latest still-image coding standard. It was designed to overcome the limitations of the original JPEG standard and provide high quality images at low bit rates. The JPEG2000 algorithm is fundamentally based on the Discrete Wavelet Transform (DWT) and Embedded Block Coding with Optimal Truncation (EBCOT). Both of the algorithms are computationally intensive and require significant...
متن کاملParallel-pass architecture for embedded block coding with optimal truncation in JPEG 2000
In this letter, we propose parallel-pass architecture for Embedded block coding with optimal truncation (EBCOT) entropy encoding in JPEG 2000. In the proposed method the time consuming sequential pass architecture is replaced with the parallel-pass approach. The experimental results show that the proposed method reduces the processing time by 22.6% as compared with the Taubman’s Kakadu architec...
متن کاملHigh Efficiency Concurrent Embedded Block Coding Architecture for JPEG 2000
Embedded block coding with optimized truncation (EBCOT) is the most important part of JPEG 2000. Due to the bit level operation and the three-pass scanning technique, the EBCOT may take more than 50% operation time in the JPEG 2000. This paper presents a high efficiency concurrent EBCOT (HECEBC) entropy encoder hardware architecture. The proposed HECEBC can concurrently process the four samples...
