CSE 220: Systems Fundamentals I
Name: SBU ID#: Recitation: Score: / 20
Consider the specification of a 32-bit ALU given below:
C1 C0 Operation 00B+1
0 1 A NOR B
1 0 AORB
1 1 SLTE(A≤B)
1. [12 pts] Complete the implementation of a 1-bit ALU to handle bits 1-30 on the diagram below (i.e., the ALUs between the LSB and MSB ALUs). Add ONLY wires, at most TWO 2:1 (1-bit selector) multiplexers and ONE 2-input gate. No other circuit elements may be added.
2. [8 pts] Give fully-simplified Boolean expressions for any of the 2:1 mux control signals and any other sig- nals in the diagram that require such expressions to be given. You may assume that complemented and uncomplemented control bits (C0, C1) are available.
