![]() ![]() Module four_to_one_mux(in0, in1, in2, in3, select0, select1, out) Here are the Flip flop, mux, and full adder headers: module full_adder(sum, cout, cin, inp1, inp2) Wire adder1in2, adder2in2, adder3in2, adder4in2 įour_to_one_mux mux1(0, 0, in, 0, add, iac, adder1in2) įour_to_one_mux mux2(0, 0, in, 0, add, iac, adder2in2) įour_to_one_mux mux3(0, 0, in, 0, add, iac, adder3in2) įour_to_one_mux mux4(0, 1, in, 0, add, iac, adder4in2) įull_adder f1(sum1, ffin1, cinadder1, acc, adder1in2) įull_adder f2(sum2, cinadder1, cinadder2, acc, adder2in2) įull_adder f3(sum3, cinadder2, cinadder3, acc, adder3in2) įull_adder f4(sum4, cinadder3, 0, acc, adder4in2) ĭ_flip_flop dff1(ffin1, x2, carry, carrynot, clc) ĭ_flip_flop dff2(sum1, x2, acc, qn2, clearcarry) ĭ_flip_flop dff3(sum2, x2, acc, qn3, clearcarry) ĭ_flip_flop dff4(sum3, x2, acc, qn4, clearcarry) ĭ_flip_flop dff5(sum4, x2, acc, qn5, clearcarry) Output carry, carrynot, qn2, qn3, qn4, qn5 Below is what I have do far: module adder_and_accum(add, clb, clc, iac, x2, in, acc, carry, carrynot, qn2, qn3, qn4, qn5) reg wire.I am creating an adder and accumulator using structural only. Shift register Adder FSM Shift register Shift register Sum = A+B Clock Figure 1: Block diagram of a serial adder reset ab - 01/10 ab=00 G1 s=1 ab = ) 01/10 ab 00 ab = 11 ab - 00 ab = 00 G: carry-in = 0 H: carry-in = 1 11 ab ab = 01/10 Figure 2: Moore type FSM of a serial adder Also, include detailed discussion of the results obtained. from specifications to verification processes). ![]() In your report, please clearly explain the design flow (i.e. Prove that your design is working by using Model Sim for simulation. Write a Verilog code for the serial adder based on the FSM in Figure 2. The serial adder can be implemented using an FSM as given in Figure 2. ![]() Figure 1 shows a block diagram of a serial adder. Hence, for some applications that the speed is not of great importance, then a cost-effective option is to use a serial adder, in which bits are added a pair at a time. A parallel adder is fast, but complex and high in cost. Transcribed image text: A parallel adder has been introduced in Chapter 3. ![]()
