An efficient architecture of 1D CSDA MST core is designed using CSDA (Common Sharing Distributed Arithmetic) to achieve high-throughput rate supporting multi-standard transformations at low cost. Common Sharing Distributed Arithmetic (CSDA) combines factor sharing and distributed arithmetic sharing techniques, efficiently reducing the number of adders for high hardware-sharing capability. Conventional Distributed Arithmetic (DA) is popular in Application Specific Integrated Circuit (ASIC) design, and it features on-chip ROM to achieve high speed and regularity. In this paper, a new DA architecture called NEDA is proposed, aimed at reducing the cost metrics of power and area while maintaining high speed and accuracy in Digital Signal Processing (DSP) applications.
