Simulating CPU Performance in C

Aim: To write a program that simulates the performance of an 8-bit CPU. You are required to define an instruction set, describe the simulator algorithm and write the code to implement the simulator. Suggested Approach: 1. Define the number of bits needed for an instruction set. ie. 3 bits will support 23=8 instructions. 2. Select the required instructions: ie Instruction Mnemonic RTL definition Load Acc from memory LDA N [A][M(N)] Store Acc in memory STA N [M(N)] [A] Add memory to Acc. ADD N [A] [A]+[M(N)] Branch to location N BRA N [PC] N If A=0, Branch to location N BEQ N IF [A]=0 THEN [PC] N 3. Define the algorithm needed for simulation 4. Select a programming language ie (C) 5. Design a simulator that can simulate the functionality of your CPU 6. Test your design 7. Discuss and conclude Deliverables. A concise typed report (max 10 pages excluding any listings) describing the design and implementation of the CPU simulator. Deadline is 03-05-2010.
