Spim – a self-contained simulator that runs MIPS32 assembly language programs. spim also provides a simple debugger and minimal set of operating system services.
Spim is a machine simulator based on the MIPS processor, incl. IRIX, Windows NT, Windows CE, Linux, BSD, UNIX, SINIX, QNX and RISC/OS. It supports 32 and 64 bit architecture. Available for UNIX, Linux, Mac OSX and Windows platforms. The program has a convenient GUI running on Qt – QtSpim.
It reads and executes assembly language programs written for this processor. Spim also provides a simple debugger and minimal set of operating system services. Spim does not execute binary (compiled) programs.
Spim implements almost the entire MIPS32 assembler-extended instruction set. (It omits most floating point comparisons and rounding modes and the memory system page tables.) The MIPS architecture has several variants that differ in various ways (e.g., the MIPS64 architecture supports 64-bit integers and addresses), which means that Spim will not run programs for all MIPS processors.
Spim comes with complete source code and documentation.
