A new memory data scheduling scheme is used for designing a two-dimensional discrete wavelet transform (2D-DWT) core for ASIC implementation. This scheme reduces by 20 to 30% the overall switching activity in the 2D-DWT core and hence leads to lower power consumption at the expense of a slight reduction in the quality of reconstructed images and a slight increase in the chip area. This scheme is particularly useful in applications such as wireless Internet and laptop computers, in which picture quality can be traded-off for reduced power consumption.
