This is the MIPS ArchC 2.2 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 mips.ac -abi (create the simulator) make -f Makefile.archc (compile) mips.x --load= [args] (run an application) The [args] are optional arguments for the application. There are two formats recognized for application : - ELF binary matching ArchC specifications - hexadecimal text file for ArchC To generate binary utilities use: acbingen.sh -i -a mips.ac This will generate the tools source files using the architecture name (if omitted, mips1 is used), copy them to the binutils source tree, build and install them into the directory (which -must- be an absolute path). Use "acbingen.sh -h" to get information about the command-line options available.
