Several comments on homework 6.
  • On a write miss in a write-back memory update policy, the cache controller first reads the block from memory for the address that missed, and then does the update. It's called 'read allocate'. This is what you should implement on a write miss. This is something we should have explained in the assignment, but didn't notice we had omitted it. My apologies. And thanks to those of you who brought this to our attention.
  • It's fine if you want to turn in homework 6 on the last day of class, Wednesday, December 11. Just remember that that is the day the cache and virtual memory problems are due.
  • As you know, SMOK only implements 4B memories. You can emulate an 8B block by either having two memory interfaces, one for each word, or making two consecutive accesses to a 4B memory. We don't care which.
    The mailing lists are set up. Each student should subscribe to cse378 and cse378-staff. cse378 will be for your discussion about homeworks, general questions, etc. cse378-staff will be used by the professor and TAs to announce homework changes, schedule updates, and the like. Students should never send mail directly to cse378-staff.

    To subscribe to a mailing list the old-fashioned way, send email to cse378-request@cs with a blank subject. The body of the text should be: "subscribe cse378" with nothing else. You should also send an email to cse378-staff-request@cs with a body of "subscribe cse378-staff". You should not send the request to majordomo@cs
    Alternatively, you can go here for 378 and here for 378-staff.
