Unformatted text preview: Although there are two slightly different 1-bit ALUs pictured in Figure B.5.10, you actually only need to build one, since we will not be using overflow detection. Your 1-bit ALU should be like the one in the top of the figure, except with a SET output added as in the bottom of the figure. Note that the OPERATION input is two bits wide, which requires the use of a bus. Create the OPERATION bus as you learned in Lab 3. The separate bits of the OPERATION signal need to be wired to the selector inputs (S0 and S1) of your 4-to-1 multiplexer (M4_1E). Also remember to name the individual wires of the bus to be OPERATION (0) and OPERATION (1). When you have completed the schematic for your 1-bit ALU, make it into a symbol called ALU_1 for use in the next level of your design. As far as your report is concerning, comprehensively analyze the features of the 1-bit ALU and achieve at least 4 kinds of features in simulation....
