... this paper, we propose a method for the e#ective implementation of specific circuits with real coe#cients onDS++ DS+Chasspecialhardware such as a complex multiplier so that a complex calculation can be performed with only one instruction First, we show that nodes with two real coe#cient input branches can be implemented by complex multiplications We apply this implementation to 2D circuits and transversal circuits with real coe#cients Next, we introduce a new computational mode (Advanced mode) and a new multiplier intoPSR a kind of DS+[ which has been proposed already, in order to process the circuits e#ectively The effectiveness of the proposed method is shown by simulation in the last part.
