A Novel Reconfigurable Low Power Distributed Arithmetic Architecture for Multimedia Applications

The use of reconfigurable cores in system on chip (SoC) designs is increasingly becoming a trend. Such cores are being used for their flexibility, powerful functionality and low power consumption. Distributed arithmetic (DA) is a powerful algorithm widely used in many fields of multimedia for its efficiency. This paper presents a novel reconfigurable adder-based architecture for DA to realize the inner product which is the key computation in many digital signal processing applications. 1D DCT is mapped onto the architecture. Compared with some existing ASIC designs, the new architecture achieves good performance in area, speed and power.
