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. © 2001 IEEE.Architecture designs; Context formations; Efficient architecture; Embedded block coding with optimized truncation; Pixel skipping; Process speed; Processing time; Speed-up method; Block codes; Image analysis; Image coding; Optimization; Systems analysis; Group-of-column skipping (GOCS); Embedded systemsconference paper10.1109/vtsa.2001.9345142-s2.0-0035018998
