In this brief, we present an efficient design of a shared architecture to compute two 8-point Daubechies wavelet transforms. The architecture is based on a two-level folded mapping technique that is developed on the factorization and decomposition of transform matrices exploiting the symmetrical structure. The chip occupies a 2.08-mm2 silicon area, runs at 100 MHz, and consumes 4.51 mW of power in 0.18-m CMOS technology.
