Abstract—This paper proposes a VLSI architecture of JPEG2000 encoder, which functionally consists of two parts: Discrete Wavelet Transform (DWT) and Embedded Block Coding with Optimized Truncation (EBCOT). For DWT, a Spatial Combinative Lifting Algorithm (SCLA) based scheme with both 5/3 reversible and 9/7 irreversible filters is adopted to reduce 50% and 42% multiplication computations respectively compared with the conventional Lifting Based Implementation (LBI). For EBCOT, a Dynamic Memory… CONTINUE READING
