Thursday, Nov. 10th: Speculative Versioning Cache (Patrick)
Tuesday, Nov. 29th: DIVA (Elham) / Razor (Mark)
Note that the assignment assumes an earlier version of simplescalar
Support files (use “bunzip2 –c file | tar xvf - ” to uncompress/untar files ending in tar.bz):
0. Download and install cygwin from www.cygwin.com – Make sure to include the development tools
1. Simplescalar “MIPS” gcc port (9.5M)
a. Install with: “bunzip2 –c ss-gcc.usrlocal.tar.bz | tar xvf – “
b. Include /usr/local/bin in your path
c. Compile programs using “ss-gcc”
2. Simplescalar Report: Describes Simplescalar (103K)
Tutorials available at : http://www.simplescalar.com/docs.html
3. MIPS Instruction Set Reference, (653K)
a. Note that Simplescalar implements a MIPS-like instruction set that uses 64-bits per instruction (see previous report)
4. Simplescalar source code (slightly modified – 350K)
Please note that the assignment assumes a slightly different version of simplescalar. You are responsible for figuring out the minor differences and adapt your code accordingly.
Please use cc1.lit.ss from the first assignment. Where needed report the summary of your results along with comments explaining why you think the results are as they are.
Don’t forget question “0. What is the difference between ‘baseline’ and ‘ideal’ in Select-Free Instruction Scheduling Logic”?
