Abstract :
Four-operands Real Multiply Accumulation (4op-RMA), which has been proposed previously, is a method for implementing transversal circuits, direct form circuits and 2D type circuits with real coefficients using a complex multiplier. However, it has not been applied to lattice circuits so far. In this paper, we propose an enhanced method for lattice circuits with 40p-RMA. The lattice part can be calculated by a 4op-RMA operation which corresponds to a complex multiplication
