Distributed Arithmetic (DA) has been widely used in inner product calculation with one fixed vector. In ROM-based DA, the variable input is decomposed into bit level but in adder-based DA the fixed vector is decomposed into bit level instead of the variable input. The adder-based DA algorithm takes advantage of shared partial sum-of-products in the inner product calculation and nonzero bits in the fixed input to achieve high speed and low area design. 8-point Discrete Cosine Transform (DCT) architecture using adder-based DA needs 30% of ROM area and has faster speed compared with conventional ROM-based DA.
