Unformatted text preview: Problems 1. Begin by drawing the schematic of the the full adder as described in section 8.6 of the text. A B Cin A A B Cin Cin B S Cout Last updated: 11/4/2006 2. Now incorporate your single bit adder into a single bit ALU. This ALU contains a 4-to-1 mux with inputs of A , A+B (addition), A AND B , and NOT A . Draw the Logic Diagram for this single bit ALU. The inputs should include A , B , Cin , and C[1:0] (control). The outputs should include Out and Cout . 3. Now draw a symbol for this 1-bit ALU and show how you would combine 4 of them into a 4-bit ALU.
