# Page-Table-Simulator

## Instructions to Run:

***Assuming Page Table state from PT_A.txt***

1. **Running Part A: ptsim**

    - Inputting one virtual address at a time via CLI.

        - `$ make ptsim`

        - `$ sh ptsim tests/PT_A.txt`

        - *Enter (one by one) virtual addresses to translate.*

        - *Crtl+D to terminate.*

    - Using I/O redirection to translate addresses from input file and diff the expected output.

        - `$ make ptsim`

        - `$ sh ptsim tests/PT_A.txt < tests/test_input1.txt > tests/actual_output/ptsim_PT_A_output1.out`

        - `$ diff tests/expected_output/ptsim_PT_A_output1.txt tests/actual_output/ptsim_PT_A_output1.out`

        - *No Diff (hopefully)*

2. **Running Part B: ptsim-clock**

    - Inputting one virtual address at a time via CLI.

        - `$ make ptsim-clock`

        - `$ sh ptsim-clock tests/PT_A.txt`

        - *Enter (one by one) virtual addresses to translate.*

        - *Crtl+D to terminate.*

    - Using I/O redirection to translate addresses from input file and diff the expected output.

        - `$ make ptsim`

        - `$ sh ptsim-clock tests/PT_A.txt < tests/test_input1.txt > tests/actual_output/ptsim_clock_PT_A_output1.out`

        - `$ diff tests/expected_output/ptsim_clock_PT_A_output1.txt tests/actual_output/ptsim_clock_PT_A_output1.out`

        - *No Diff (hopefully)*

3. **Quick Testing of Differences (Hard Coded for specific I/O).**

    - `$ make check`

    - *No Diff (hopefully)*

## TODO:

- Have the page table as a dictionary {key:"101", value:[V, P, F, U]}.

## Gondree's README Content.

The files `pt-sim.sh` and `pt-sim-clock.sh` are wrapper files you should modify to call your executables.

You should add Makefile logic so that your program can be run with commands like:

    $ make ptsim

    $ make ptsim-clock

    $ sh ptsim test/aPageTableFile < test/anInputFile

    $ sh ptsim-clock test/aPageTableFile < test/anInputFile
