3. In this assignment, you will explore the fundamentals of a simple 2-bit von Neumann architecture, including its hardware components, instruction execution, and assembly programming. The architecture will support a limited instruction set, mem- ory for both instructions and data, and a control unit to manage execution. You will design a 2-bit von Neumann CPU that supports the following instructions: Q3-1: Describe the hardware components needed for this 2-bit von Neumann CPU and their interconnections. You may include a simple block diagram to illustrate the architecture. Q3-2: Instruction Execution For each instruction (LOAD, STORE, ADD, ADDi), explain: • Which hardware components in your design will be used and how they are interacting with each other • Control signals activated during execution 1 Opcode Mnemonic 00 LOAD 01 STORE 10 11 ADD ADDi Description Load the value from a memory address Store the value from the computing unit to a memory address Add the value from memory addresses Add the immediate value (constant) with a value at a memory address Table 1: Instruction Set for the 2-bit von Neumann CPU Q3-3: Writing a Simple Assembly Program Write an assembly program to compute: t=a+b t=t+1 where a and b are stored in memory at addresses 00 and 01, and the result t is stored at 10. Discuss how the program will be executed and how the hardware components will be utilized.
