This project is based on the materials developed by Textbook authors.
You can download the original Y86-64 tools and documentation from
http://csapp.cs.cmu.edu/3e/sim.tar
We have slightly modified the original toolset to make you focus on the
sequential implementation of Y86-64 architecture and to facilitate the
automatic grading.
The followings summarize some of the changes made:
- Makefile has been modified for "make handin".
- The original misc/isa.c file is divided into misc/isa.c and misc/isacore.c
- The original pipe/psim.c file is divided into pipe/psim.c and seq/psimcore.c
- misc/Makefile and pipe/Makefile have been changed to reflect the addition of
misc/isacore.c and seq/ssimcore.c files.
- Some necessary modifications have been made in misc/yas-grammar.lex, misc/isa.h,
and misc/isa.c files to support mulq and rmmovb/mrmovb instructions.
- A new control signal called 'mem_byte' has been added to the data memory.
The mem_byte signal should be set to 1 for rmmovb and mrmovb instructions.
- pipe-1w.hcl, pipe-broken.hcl, pipe-btfnt.hcl, pipe-lf.hcl, pipe-nt.hcl, and
pipe-std.hcl files in ./pipe arre moved (not used in this project)
- pipe/pipe-nobypass.hcl is renamed to pipe/pipe-stall.hcl
- Stuffs related to ncopy.ys have been removed in the ./pipe directory
- Several test programs that use mulq and rmmovb/mrmovb instructions are added
in the ./y86-code directory.
- The ./seq directory has been removed (not used in this project).
- The instruction limit is set to 1000000 in pipe/psim.c
- A new option '-s' is added in the pipe/psim.c file for printing output for
automatic grading server (enabled by -DSNU flag in pipe/Makefile).
Have fun!
