Abstract

This paper presentsprecision-aware approaches and associated hardware implementations for performing the DWT. By implementing BP architecture and also presents DS design methodologies. These methods enable use of an optimal amount of hardware resources in the DWT computation. Experimental measurements of design performance in terms of area, speed, and power for 90-nm complementary metal–oxidesemiconductor implementation are presented. Results indicate that BP designs exhibit inherent speed advantages than DS design.

Keywords

Fixed point arithmetic, image coding, very largescale integration (VLSI), wavelet transforms.
