A New Scalable Recursive MAC Design for Filtering Applications
In this paper, the authors propose a design of an application specific filter design for low power solutions in recursive coding system in which MAC was the main operation in filtration process. The realization of this MAC operation is carried out in recursive manner i.e. a recursive multiplication and addition operation is carried out. The conventional recursion results in multiple accumulation operation in successive clocks of duration amounting to that of an addition time, so that the accumulation of N successive input words are performed in N clock cycles.
