In this paper, an efficient algorithm for concurrent computation of two real multiplications and/or two real additions usually required for high-throughput image and video coding applications is described. The proposed algorithm is mapped onto a novel concurrent dual multiplier-dual adder cell based on carry-save 4:2 compressors. A detailed performance analysis of the the proposed cell shows reductions ranging from 15% to 60% in the computation time and area when compared with the conventional processing elements making it highly attractive for VLSI implementation.
