Implementation of Integer Wavelet Transform on Software Configurable Processor

Abstract

Imaging in medicine has become so common that it is necessary that we have an image compression standard for the medical images. The JPEG 2000 standard is the latest from the JPEG group. The JPEG 2000 is more computationally intensive than the JPEG. In this work we propose a faster implementation of the integer wavelet transform used in the JPEG 2000 standard. We have implemented the integer wavelet transform on the Stretch's Software Configurable Processor (SCP). A comparison of a Pentium based implementation and the SCP based implementation was done. In our work we have found that the wavelet transform calculations took nearly 35 times less number of clock cycles on the SCP when compared to one with the Pentium implementation.
