Parallel-pass architecture for embedded block coding with optimal truncation in JPEG 2000

چکیده
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 architecture of EBCOT. © 2012 Society of Photo-Optical Instrumentation Engineers (SPIE).

Analysis 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 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...
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 کاملA Low Power and High Performance Ebcot Architecture of Jpeg2000 Encoding
We propose an architecture for Tier-1 of Embedded Block Coding With Optimized Truncation (EBCOT) in the JPEG2000 standard. The architecture is composed of a 16-bit parallel context generator and a 3-stage pipelined binary arithmetic encoder. The former is designed for low power consumption. The later is used to achieve an high throughput. The design is verified on an AMBA-based system as an acc...
متن کاملA 158 MS/s JPEG 2000 Codec with a Bit-Plane and Pass Parallel Embedded Block Coder for Low Delay Image Transmission
This paper describes a 158 MS/s JPEG 2000 codec with an embedded block coder (EBC) based on a bit−plane and pass−parallel architecture. The EBC contains bit−plane coders (BPCs) corresponding to each bit−plane in a code−block. An upper BPC transfers significance states and sign bits to a lower BPC via a first−in−first−out buffer (FIFO) to synchronize BPCs themselves. The upper and the lower bit−...
