Abstract
A new distributed arithmetic (DA) method called adder-based DA is proposed in this paper to evaluate the inner products of vectors. This approach needs only 13% of transistor count and 30% of ROM area with comparable performance. A 2D inverse DCT (IDCT) chip is designed and implemented on the adder-based DA in 0.8 /spl mu/m SPDM CMOS technology to verify the correctness and efficiency of the method.
