Consider executing the following code on the pipelined datapath that we discussed in class. During the 5th cycle, which registers arc being read and which registrars) will be written (using the register file)? Explain what the forwarding unit is doing during the 5th cycle of execution. Which registers arc being compared? List all pairs of registers that are compared during the 5th cycle for the forwarding unit. (First, you need to determine which instruction's values arc in the EX/MEM, which instruction's values are in the MEM/WB register, and which instruction's values are read from the ID/EX register during the 5th cycle. Then check the conditions for forwarding.) Explain what the hazard detection unit is doing during the 5th cycle of execution. Which registers are being compared? List all pairs of registers that arc compared during the 5th cycle for the hazard detection unit. (You need to determine which instruction's values arc in the IF/ID and which instruction's values are in the ID/EX register during the 5th cycle. Then check the conditions for the hazard detection.)
