This is the MIPS-I ArchC functional model.

This model has the system call emulation functions implemented,
so it is a good idea to turn on the ABI option.

To use acsim, the interpreted simulator:

    acsim mips1.ac -abi -dy             (create the simulator)
    make -f Makefile.archc              (compile)
    mips1.x --load=<file-path> [args]   (run an application)

To use accsim, the compiled simulator:

    accsim mips1.ac -abi -dy <file-path> (create specialized simulator)
    make -f Makefile.archc               (compile)
    mips1.x [args]                       (run the application)

The [args] are optional arguments for the application.

There are two formats recognized for application <file-path>:
- ELF binary matching ArchC specifications
- hexadecimal text file for ArchC


To use acasm, the assembler generator:

    asmgen.sh mips1.ac <assembler_name> (generate the assembler 
                                         source files) 
    proceed to build it using the GNU autotools (configure, make all-gas, 
                                                 make install-gas)
