CS 207: Computer Organization and Architecture

Problems: more digital logic, plus some performance evaluation

Do problems B.1, 2, and 24 (on the textbook's CD).
Design and draw a 1-bit 4-function ALU with the following specifications. The unit should have five input lines: (1) A, a data line, (2) B, another data line, (3) Cin, the carry-in for addition, and (4-5) S0 and S1, a pair of control lines that determine the operation performed by the ALU. There should be two output lines--the result R, and the carry-out Cout. R should depend on the input as follows:
```
       S1 S0           R
       ============================
       0  0            NOT A      
       0  1            A AND B
       1  0            A OR B
       1  1            A + B + Cin (where + is addition rather than OR)
    
```
Do problems 4.1-6 (4.4 and 4.5 are on the CD).
