Homework #8 February 28, 2012 1 Homework #8 due March 12 at noon ECE 15a Winter 2012 (5p)1. Build the 8-to-3 priority encoder using two 4-to-2 priority encoders and tri-state buffers. (5p) 2. A combinational circuit is defined by the following three Boolean functions: F1(x,y,w,z) = m(2,8,10) F2(x,y,w,z) = m(2,3,7,11) F3(x,y,w,z) = m(2,4,6,7) Implement the circuit using a PLA. Minimize the numer of product terms. (5p) 3. Implement F1, F2 and F3 from problem 2 using a 4-to-16 decoder and NOR gates. (5p) 4. Implement the following Boolean function using a 2-to-1 multiplexer and two 3-variable LUTs: F(A,B,C,D) = (1,2,5,6,7,9,13,15). Specify the functions realized by each LUT. 5. Implement a full adder with (10p) (a) two 4-to-1 multiplexers. (5p) (b) only 2-1 muxes. 6. A combinational circuit is defined by the following Boolean functions: A(x,y,z,w) = (4,5,12,13) B(x,y,z,w) = (5,6,13,14) C(x,y,z,w)= (6,7,14,15) D(x,y,z,w)= (4,6,7,12,14,15) / * Note that one variable can be eliminated*/
