Design Introduction
JPEG2000 is a recently standardized image compression algorithm that provides significant
enhancements over the existing JPEG standard. JPEG2000 differs from widely used compression
standards in that it relies on discrete wavelet transform (DWT) and uses embedded bit plane coding of
the wavelet coefficients [1]. Due to the bit-oriented processing techniques used in the standard, full
implementation via software is inefficient, making embedded processing slow on standard
microprocessors
