Abstract

The multiplier free approximate DCT transform is proposed. The transform offers superior compression performance at very low circuit complexity. Such approximations can be realized in digital VLSI hardware using additions and subtractions only, leading to significant reductions in chip area and power consumption compared to conventional DCTs and integer transforms. The proposed transform requires only 14 addition operations and no multiplications.
