1. Assume numbers are represented in 8-bit 2's complement, show the calculation in binary and specify the flags, if set (1) or reset (o). 124 4 Unit 2- Floating-point conversion and Review of logic Design. 1. Convert -11.13 to floating-point format. 2. Design a circuit to decode 1001. 3. Design a 4 to 1 multiplexer. Unit 3- ALU Design 1. Design a 1-bit full adder that can perform the following operations. You can use only one full adder Specify the operation code. Operation Code A plus B A plus 0 A plus AB AB 2. Extend the 1-bit ALU to 2-bit. 3. Show the result of logical right shift and arithmetic right shift for the following bit patterns: Bit patternArithmetic right shift Logical right shift 1100 0100 0011 Chapter 4 MARIE 1. What are the main functions of the CPU? 2. How is the ALU related to the CPU? What are its main functions? 3.
