I need someone who is good with mips programming please! **MIPS Single-Cycle CPU Diagram Explanation**The image presents a schematic diagram of a MIPS single-cycle CPU, which is designed to execute instructions in a single clock cycle. The CPU includes various components:1. **Program Counter (PC):** This component points to the address of the next instruction to be executed.2. **Instruction Memory:** It stores the instructions to be executed by the CPU. The instruction is fetched based on the address provided by the PC.3. **Control Unit:** This unit generates control signals based on the instruction fetched. Signals include `MemtoReg`, `MemWrite`, `Branch`, `ALUControl`, `ALUSrc`, `RegDst`, and `RegWrite`.4. **ALU (Arithmetic Logic Unit):** The ALU performs arithmetic and logical operations. It takes two inputs (`SrcA` and `SrcB`) and produces an output (`ALUResult`). The result is used to determine if the outcome is zero.5. **Register File:** Contains registers A1, A2, RD1, RD2, and WD3. It provides the operands to the ALU and stores the result of computations.6. **Data Memory:** This component is used for reading and writing data. The `ReadData` signal outputs data read from memory.7. **Sign Extend:** Extends the immediate values to a specific bit length required for computations.8. **Shift Left 2 (<<2):** Shifts the input value left by two bits, used in calculating branch addresses.9. **Multiplexers (shown as boxes with multiple inputs and one output):** They select input signals based on control signals (e.g., `PCSrc`, `ALUSrc`).10. **PCPlus4:** Adds 4 to the current PC to fetch the next sequential instruction.11. **PC Branch Logic:** Determines if a branch should be taken based on the `Zero` result from the ALU.**Q1.1 lw Instruction Execution**The task is to outline the steps in low-level instruction execution for the “lw” (load word) instruction in this MIPS architecture, often focusing on the control signal interactions, data path selection, and operation of each involved hardware component.Overall, this schematic is essential for understanding the flow of data and control in the execution of instructions within a MIPS single-cycle CPU architecture. **Q1.2 HW Signal Matching Instructions***3 Points*When an instruction was CORRECTLY executed on the MIPS single-cycle CPU, we observed MemtoReg = 0, RegDst = 0, and MemWrite = 0. Select all the correct answers below:- [ ] This instruction might be sw- [ ] This instruction MUST NOT be sw- [ ] This instruction MUST be addi- [ ] This instruction might be addi- [ ] This instruction might be slt- [ ] This instruction might be beq- [ ] This instruction MUST NOT be lwProvide your explanations for each of the options (why it is correct or incorrect).
