MIPS SIMULATOR : The SPIM operating system
The
SPIM simulator comes with a rudimentary operating system, which allows the
programmer usage of common used functions in a comfortable way. Such functions
are invoked by the syscall-instruction. Then the OS acts depending on the
values of specific registers
MIPS SIMULATOR : Type of Simulator
TYPE OF MIPS SIMULATOR
The newest version of Spim is
called QtSpim, and unlike all of the other version, it runs on Microsoft
Windows, Mac OS X, and Linux the same source code and the same user interface
on all three platforms! QtSpim is the version of Spim that currently being
actively maintaned. The other versions are still available, but please stop
using them and move to QtSpim. It has a modern user interface, extensive help,
and is consistent across all three platforms.
QtSpim makes my life far easier,
and will likely improve yours and your students' experience as well. A compiled, immediately
installable version of QtSpim is available for Microsoft Windows, Mac OS X, and
Linux can be downloaded from: https://sourceforge.net/projects/spimsimulator/files/.
GXemul
(formerly known as mips64emul) is a computer architecture emulator being
developed by Anders Gavare. It is available as free software under a revised
BSD-style license. In 2005, Gavare changed the name of the software project
from mips64emul to GXemul. This was to avoid giving the impression that the
emulator was confined to the MIPS instruction set, which was the only architecture
being emulated initially.
Although
development of the emulator is still a work-in-progress, since 2004 it has been
stable enough to let various unmodified guest operating systems run as if they
were running on real hardware. Currently emulated processor architectures
include ARM, MIPS, M88K, PowerPC, and SuperH. Guest operating systems that have
been verified to work inside the emulator are NetBSD, OpenBSD, Linux, HelenOS,
Ultrix, and Sprite.
Apart
from running entire guest operating systems, the emulator can also be used for
experiments on a smaller scale, such as hobby operating system development, or
it can be used as a general debugger.
MARS (MIPS Assembler and Runtime Simulator)
MARS is a lightweight interactive development environment
(IDE) for programming in MIPS assembly language, intended for educational-level
use with Patterson and Hennessy's Computer Organization and Design. It was developed by Pete Sanderson and Kenneth Vollmar at
Missouri State University.
QEMU (short for Quick Emulator)
It is a free and open-source
hosted hypervisor that performs hardware virtualization (not to be confused
with hardware-assisted virtualization). QEMU is a generic and open source machine emulator and
virtualizer. When used as a machine emulator, QEMU can run OSes and programs
made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC).
By using dynamic translation, it achieves very good performance.
QEMU is a hosted virtual machine monitor: It emulates CPUs
through dynamic binary translation and provides a set of device models,
enabling it to run a variety of unmodified guest operating systems. It also can
be used together with KVM in order to run virtual machines at near-native speed
(requiring hardware virtualization extensions on x86 machines). QEMU can also
be used purely for CPU emulation for user-level processes, allowing
applications compiled for one architecture to be run on another..

MIPS Simulator (Introduction)
SPIM
is a MIPS processor simulator, designed to run assembly language code for this
architecture. The program simulates R2000 and R3000 processors, and was written
by James R. Larus while a professor at the University of Wisconsin-Madison.[2]
The MIPS machine language is often taught in college-level assembly courses,
especially those using the textbook Computer Organization and Design: The
Hardware/Software Interface by David A. Patterson and John L. Hennessy (ISBN
1-55860-428-6).
The
name of the simulator is a reversal of the letters "MIPS".
SPIM
simulators are available for Windows (PCSpim), Mac OS X and Unix/Linux-based
(xspim) operating systems. As of release 8.0 in January 2010, the simulator is
licensed under the standard BSD license.
In
January, 2011, a major release version 9.0 features QtSpim that has a new user
interface built on the cross-platform Qt UI framework and runs on Windows,
GNU/Linux, and Mac OS X. From this version, the project has also been moved to
SourceForge for better maintenance. Precompiled versions of QtSpim for Linux
(32-bit), Windows, and Mac OS X, as well as PCSpim for Windows are provided.
