Q4. Label the datapath, input bits to the data lines, and enable the control lines for following instruction: j Loop Assume Loop is associated with value 24110 Include the proper instruction format and control signal tables. Hints: The decimal value 24110 must be converted to 28 bits: Convert to binary, then append zeros to the left. The j-format has an opcode assignment of 210 PC Add Instruction (25:0 Shift left 2 Jump address [31:0] Instruction [31:26] PC+4 [31:28] Shift RegDst left 2 Jump Branch MemRead MemtoReg Control ALUOP MemWrite ALUSrc RegWrite ALU ALU result AND Read address Instruction (25:21] Instruction [20:16] Instruction [31:0] Instruction [15:11] Read register 1 Read register 2 Write register Read data 1 Zero ALU ALU Address Instruction Memory Read data 2- result Read data Write data Instruction [15:0 Registers 32 Sign- extend Instruction [5.0] ALU control Write Data memory data Q4.
