Project: Design of a CPU System

Design a CPU System that combines and connect memory system, ALU, registers and control unit. The CPU MUST use a 16-bit instruction format where 6-bit for Opcode, 5-bit for Operand 1 and 5-bit for Operand 2 as shown below:

6 Bits 5 Bits 5 Bits

Opcode Operand 1

Operand 2

16 bits

The CPU should be able to perform the complete instruction cycle (fetch instruction (FI), decode instruction (DI) Calculate operands (CO), fetch operands (FO), execute instruction (EI), and write operand (WO). To verify the functionality of the CPU system, the students have to create test benches to demonstrate that the CPU are able to perform at least the computations as shown below:

Y = [(A+B) x C] / (D-E)

Y = [(A-B) / C] x (D+E)

Y = [ (A || B) C)] / D+E)

Y = [(A+ (B / C)] ^ (D x E)
