Abstract :
In this paper a new methodology for building up filters for the JPEG2000 standard is presented. The proposed filter architectures can be applied efficiently for both 1D forward and inverse wavelet transform implementations. They are characterized by reduced memory accesses, area, power, and the capability of progressive computation. The illustrated VLSI implementation synthesis results prove that the introduced architectures can be embedded in systems which are used in real time applications.
