Abstract

Fig. 1 shows a sequential set of IF statements in flow chart form to be implemented in logic. Normally, the logic is implemented from top to bottom, i.e., G1.D1+G1.G2.D2+G1. .... G(N-1).GN.DN+G1. .... GN.D(N+1). Instead, the sequence of IF statements is directly mapped into a corresponding sequence of 2-way SELECT functions with a bottom to top flow of logic, as shown in Fig. 2.
