The Control Unit class is responsible for decoding instructions and generating control signals. • The decode_instruction method parses the instruction string into individual components. • The generate_control_signals method, in this simple design, doesn't specify control signals. 1.3 Register File class RegisterFile: def __init__(self, num_registers): self.registers = [0] * num_registers def read_register(self, register_number): return self.registers[register_number] def write_register(self, register_number, value): self.registers[register_number] = value 1.4 Memory Unit class MemoryUnit: def __init__(self, size): self.memory = [0] * size def read_memory(self, address): return self.memory[address] def write_memory(self, address, value): self.memory[address] = value 1.5 Instruction Set Architecture (ISA): LOAD destination, source STORE source, destination ADD destination, operand1, operand2 SUBTRACT destination, operand1, operand2 HALT Assembly Language Implementation: 2.1 Implement Key Instructions: ; Sample program to add two numbers LOAD R1, 5 ; Load value 5 into register R1 LOAD R2, 7 ; Load value 7 into register R2 ADD R3, R1, R2 ; Add values in R1 and R2, store result in R3 STORE R3, 0x100 ; Store result in memory address 0x100 HALT ; Halt the processor 2.2 Sample Program: ; Sample program to demonstrate instructions LOAD R1, 10 ; Load value 10 into register R1 LOAD R2, 5 ; Load value 5 into register R2 ADD R3, R1, R2 ; Add values in R1 and R2, store result in R3 SUBTRACT R4, R3, 2 ; Subtract 2 from the value in R3, store result in R4 STORE R4, 0x200 ; Store result in memory address 0x200 HALT ; Halt the processor
