Superscalar processor simulator for in-order and out-of-order processors. It also simulates several configurations of multiprocessors. Currently supports the MIPS instructions set.

This version has been updated to support modern compilers, libraries, and operating systems. It is derived from the version published by Milos Prvulovic for the Georgia Tech CS 6290 class. The upstream version appears to have some additional functionallity, but it has also been last updated a long time ago (2009).

You need a cross-compiler to build the binaries that are run, and you need to actually build the simulator.

You will need a c++ compiler, make, Bison, and Flex installed.

$ make -j$(nproc)

The executable can be found in ./build/sesc.

Get a cross-compiler by executing the following:

$ cd cross-compiler
$ bash ./cross-compiler.sh

This uses Crosstool-NG to build a new mips-unknown-linux-uclibc toolchain.

This toolchain is by default installed in ~/x-tools, and you must run something like export PATH=$PATH:$HOME/x-tools/mips-unknown-linux-uclibc/bin/ before building any of the MIPS binaries.

Some example usage:

$ pushd apps/Splash2/lu
$ make
$ popd
$ ./build/sesc -fn64.rpt -c ./confs/cmp4-noc.conf -olu.out -elu.err apps/Splash2/lu/build/lu.mipseb -n64 -p1

Stderr can be found in lu.err, stdout in lu.out, and various statistics in sesc_lu.mipseb.n64.rpt. A slightly more readable statistics report can be show using ./scripts/report.pl sesc_lu.mipseb.n64.rpt
