Abstract :
An ASIC implementation of spatial combinative lifting algorithm (SCLA) based 2D forward and inverse discrete wavelet transform (DWT) with both 5/3 and 9/7 filters and 5-level Mallat decomposition is proposed in this paper. This processor is fabricated in a 1.5mm times 1.5 mm die, using UMC 0.18mum CMOS technology, containing 28K gates plus 47Kbits on-chip SRAM. Test shows this chip can process at 23.29 frames/s with image resolution up to 1920times1080 pixels (YUV422 full color) under 100MHz, and consuming 50mW under a 1.8V power supply
