![Q4: Answer the following questions. [7 Marks] The single cycle implementation of MIPS is as shown below. Answer the following](http://img.homeworklib.com/questions/cf35f340-a85f-11eb-9eba-b589572b57be.png?x-oss-process=image/resize,w_560)
Homework Answers
i) The instruction is a branch instruction. Hence the addressing mode is PC relative addressing.
ii) The instruction format is I-type. Hence the addresses of S1 and S2 are located in the bits [25:16]
iii)
| Signal | Status |
| RegDst | X |
| Branch | 1 |
| MemRead | X |
| MemtoReg | X |
| ALUOp | 01 |
| ALUSrc | 0 |
| RegWrite | 0 |
Explanation:
- The signals of RegDst, MemRead, MemtoReg are don't care (X) as these values are not effected by the instruction.
- Branch is 1 as beq is a branch instruction
- ALUOp is 01 for subtaction.
- ALUSrc is 0 as the second operand comes from the register file.
iv) The value of the zero flag is 1 as Reg[S1] = Reg[S2]
v) The value of PC is 8H + 16H = 1E H
