A HIGH−PERFORMANCE MEMORY−EFFICIENT ARCHITECTURE OF THE BIT−PLANE CODER IN JPEG 2000 (ThuAmOR6)
Abstract : The paper presents a high−performance architecture of the bit−plane coder for the embedded block coding algorithm in JPEG 2000. The architecture adopts a pipeline structure and is dedicated to generate two context−symbol pairs per clock cycle. A novel method called Dynamic Significant State Restoring (DSSR) allows reduction of on−chip memories. The overall design was described in VHD...
متن کاملJPEG 2000: Overview, Architecture, and Applications
JPEG 2000 will soon be an international standard for still image compression. This paper describes that standard at a high level, indicates the component pieces which empower the standard, and gives example applications which highlight differences between JPEG 2000 and prior image compression standards. Other papers in this conference provide greater detail on specific portions of the standard ...
متن کاملAn Efficient Pipeline Architecture and Memory Bit-Width Analysis for Discrete Wavelet Transform of the 9/7 Filter for JPEG 2000
In this paper, we propose an efficient pipeline architecture for the DWT 9/7 filter defined in JPEG 2000. The proposed architecture is composed of column and row processors to perform the separable 2-D DWT. Based on the rescheduling DWT algorithm, we derive a new data flow graph to shorten the critical path. The proposed 1-D column processor requires less pipeline registers to achieve about the...

Abstract: With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a ne...
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...
