  1. Disegnare un circuito sequenziale sincrono che implementa l’algoritmo espresso dal seguente pseudo linguaggio: • If (start = 0) then • wait; • elseif(start=1) then • AR(3)  1; • endif • 2. do • if(Y=1) then • If(X=0) then • ror(AR); • else • rol(AR); • endif • endif • while((Y*[X*AR(3)+X*AR(0)] + Y)=1) • 3. Go to 1. start Y 3 2 1 0 X AR[4] CK
