CS 349 Summer, 2002: Lab Assignment

• Part A: Writing and Simulating Y86 Programs (pdf, ps)
  
  • Assigned: Tue May 21, Due Mon May 27, 11:59pm.
  • All the files you need are in /afs/cs.cmu.edu/academic/class/15349-s02/archlaba

• Part B: Extending a Sequential Y86 Processor (pdf, ps)
  
  • Assigned: Tue May 28, Due Mon June 3, 11:59pm.
  • All the files you need are in /afs/cs.cmu.edu/academic/class/15349-s02/archlabb
  • Thu May 30: There was a bug in seq_tk that caused the registers to be displayed in the wrong order. Thanks to Balaji for pointing this out. We've corrected the problem and you can get the updated code from
    /afs/cs/academic/class/15349-s02/archlabb/archlabb-handout.tar

    If you haven't started yet, this change doesn't affect you. Just follow the directions in the lab writeup.

    If you've already downloaded and expanded a version of archlabb-handout.tar, you'll need to download archlabb-handout.tar again. Be careful though. When you expand the new y86.tar file, this will overwrite your existing ./sim/seq/seq_full.hcl file. So be sure to save your work before expanding the new y86.tar file.

• Part C: Optimizing a Pipelined Y86 Processor (pdf, ps)
  
  • Assigned: Thu June 6, Due Fri June 21, 11:59pm.
  • All the files you need are in /afs/cs.cmu.edu/academic/class/15349-s02/archlabc
  • Tue June 18: Just to give you a sense of what is possible, here are the numbers for some of our solutions (all results are in units of CPE).

    	original	solution 1	solution 2	solution 3	solution 4
    len=64	16.45	9.55	6.56	5.56	5.06
    avg (len=1..64)	18.15	11.59	9.11	8.54	8.60

    Has anyone beaten those numbers?
