The following instructions are executed sequentially on a MIPS processor. Assume a non-interlocked pipeline: #1 LD R3, 3(R1) #2 LD R1, 2(R2) #3 ADD R1,

The following instructions are executed sequentially on a MIPS processor. Assume a non-interlocked pipeline: #1 LD R3, 3(R1) #2 LD R1, 2(R2) #3 ADD R1, R2, #1 #4 SUB R2, R3, R1 #5 SD R2, 0(R1) a. Identify a data dependence, anti-dependence and output dependence (if any) in the above code (what's an easy way to identify this? ) b. Between which instructions are no-ops inserted? Use the attached diagram for assistance. c. In the table below, write every case of: i. Data forwarding ii. Register write-read in one clock cycle Enter the following data: i. CC - The clock cycle when the data forwarding or register write-read is performed ii. Src - The Interstage register or Register providing the data iii. Dest Instr # - The stage or register receiving the data iv. Value - The forwarded data CC Src (ISR or Reg) Dest (Stage or Reg) Value
