MIPS Simulator
I was studying Computer Architecture Unit in 2016 2nd Semester. This project was to figure out how MIPS works. For the details, refer the .ppt file.
MIPS Simulator simulates simple MIPS. You can load binary files and execute them. In addition, you can view Registors' state so that you can monitor how the instructions go.
MIPS Simulator is CLI program. So to use this simulator, you should type appropirate prompts in the Simulator.
>>>l input means Load input file. You can replace input to the name of file which you want to load.
>>>m means Show memories. You can view addresses and values of VM of MIPS Simulator. But you have to clarify FROM WHERE TO WHERE.
>>>m 0 16 means to view values of VM from address 0 to address 16. Address argument should be a multiple of 4. Unless the argument is a multiple of 4, prompt will show Execption Occured.
You can put the argument with hex value. Just like >>>m 0x0 0x10
>>>s means Step. After you load binary instruction set, you can execute Step. In Step, MIPS simulator execute just a word instruction.
>>>sr means Set registors. You can use this instruction just like >>>m
>>>sr 7 5 means to set a value of Registor 7 to 5. First argument means the number of Registor, and Second argument means the value that you want to set.
>>>g means Go. Unlike Step, Go loops sequential instructions until MIPS Simulator meets syscall.
>>>j means Jump. You can change the value of PC(Program Counter). >>>j 0x10 means to jump 16th word so that MIPS simulator execute introduction from 16th line.
>>>x has two functions. When MIPS_simulator has loaded binary file, >>>x means to unload the binary file.
When MIPS_simulator doesn't have loaded binary file, >>>x means to exit.
