C Project: 24-bit Assembler

About

This project is an assignment in a C programming course at the open unvieristy (20465). The purpose of this project is to build an assembler for 15-instruction asssembly language, for an imaginary 24-bit CPU and 12 bits of memory size. This project was done by me.

Project instructions in the Hebrew language are added and named instructions.pdf.

For any issues, questions and ideas turn to the Issues tab.

Source structure (Modules)

1. assembler - main function definition, argv & argc processing, single file processing.
2. first_pass - contains functions for processing a single line in the first pass and a code line in the first pass.
3. second_pass - contains function for processing a single line in second pass and replacing symbol by it's address.
4. textAnalyze - contains functions for proccesing strings.
5. base - contains necessary data in order to proccess the input.
6. lists - contains functions to handle linked lists.
7. writefiles - contains methods for writing output files: *.ob, *.ext and *.ent

Usage

./assembler file1 file2 file3 ... Will start the processing of each file (specify WITHOUT extension!). No support for double-quoting file names.

Build

You may build with several tools:

1. Using CMake: run cmake --build . (you might have to run cmake --cofngiure . first) - Provides support for CLion IDE
2. Using make command (Makefile)
3. Manually (Not recommended): compile each *.c file to *.o and then compile all to a single executable using CC/GCC/CLang with -g a.o b.o .... -o exe
