Table-lookup-and-addition methods provide multiplierless function evaluation using multiple lookup tables and a multioperand adder. In spite of their high-speed operation, they are only practical in low-precision applications due to the fast increase in table size with precision width. In this brief, we present two methods for table size reduction by decomposing the original table of initial values into two or three tables with fewer entries and/or smaller bit width. The proposed table… CONTINUE READING
