Q1. Rewrite/reorder the original code to minimize the number of stalls to your best ability. This will in turn reduce the number of cycles needed to complete the program and should lower the CPI. Record these 4 values (Cycles, Instructions, CPI, and RAW stalls) exactly from the "Statistics" window and include them in a comment in your code. Save the files as "SID_Assign4_1.s". Some things to note: The calculated CPI is not 100% correct as it doesn't compensate for the pipeline startup and flush times. To calculate a more accurate CPI, subtract 5 from Cycles first, then divide by Instructions. The number of branch stalls can be calculated as: Cycles Instructions -Raw Stalls - 5 Go to the menu "Configure" -> "Settings" and the "Main Settings" tab and check "Enable forwarding"; Press OK. Re-load the original code and run it. The number of stalls should be far less than before turning on forwarding Q1.
