A highly efficient VLSI architecture for the (9/7) 2-D DWT based on a lifting scheme is presented in the paper. The proposed architecture processes the row and column transforms simultaneously, eliminates the memory buffer for the column transform coefficients. The hardware utilization is improved up to 100% by processing two independent data streams together using shared arithmetic functional blocks...
Register file is needed to work in high speed for high performance superscalar processors to execute multiple parallel instructions. A 10-read 6-write write-through register file, customized in 1.8V 0.18mum CMOS technology, is introduced here, every port of which can be accessed individually. It comprises two arrays of modified 16-port memory cells, some low-power SCL decoders and a local clock generator,...
