ABOUT SimIt-MIPS

SimIt-MIPS is a research tool for simulating user-level MIPS32 programs. It supports all three common simulation styles: interpretation, static-compiled simulation, and dynamic-compiled simulation. It offers very high simulation speed and has been tested on IA32 Linux platforms using SPEC CPU benchmarks. SimIt-MIPS is free, open-source software under the GNU General Public License.

SimIt-MIPS features:

• Built-in debugger
  The '-d' flag enables a simple debugging interface, allowing one to step through a program and to observe register/memory values.


• GDB interface
  The '-gdb' switch enables interfacing with GDB for more advanced debugging. GDB GUIs such as DDD can be used.


• Static-compiled simulation
  It is capable of translating a MIPS32 program into an equivalent IA32 program. The resulting program simulates around 200 million MIPS32 instructions per second.


• Dynamic-compiled simulation
  A special simulation technique that uses GCC to do run-time binary translation is implemented. The technique offers slightly slower simulation speed than static-compiled simulators. But it is more convenient to use and supports simulating self-modifying code.
