Abstract :
The paper presents optimal data transfer and buffering schemes for a JPEG2000 encoder. The data transfer scheme combines bit-level zero run-length coding and addressing mode to reduce data transfer time between discrete wavelet transform (DWT) and embedded block coding with optimized truncation (EBCOT) to 21%. Furthermore, this data transfer scheme also helps in word-to-bitplane data format conversion from DWT to EBCOT. On the other hand, by jointly considering the coding flow of both lifting-based DWT and EBCOT with different design parameters, the reduction in total buffer requirement for both DWT and EBCOT can be up to a factor of 4.22.
