Question 3: Single-cycle Datapath (15 points) The following 32-bit MIPS instruction is fetched from the instruction memory: 001101 01010 01101 1010001110110100 Assume the data memory contains all zeros and the registers have the following values when the instruction is fetched ('0x' below means hex, otherwise when there is no '0x' it means decimal): Register $at $al $a3 $v1 $t2 $t5 $ra $v0 268695321 1092 OXDEADBEEF 933 0x40100000 Value 0 0xB612 320 320 a) Write the complete MIPS instruction (including all the involved registers, and the constant if there is any) that corresponds to the given 32-bit MIPS machine code.

There are 2 major changes in this datapath. First, we added a "Zero extend" unit (oval) that is capable of zero extending the imm value. Second, we added a 1-bit "ZeroExt" control signal with a corresponding multiplexer. Assume we are executing the instruction fetched in part (a). [31-01 Control ALUOP A. Read B.

b) The labels A, B, C, D, E, F, G, and H in the datapath above indicate certain locations along the datapath. Find the data (in binary format) in the datapath for each of the labels. Note the data are with different bit widths (i.e. number of bits used) (8 points) A = B = C= D= E = F = G= H = c) Derive the value of label I in above diagram. Show your step(s) clearly otherwise no point will be given. Write the value of label I in 32-bit binary format (3 points)
