Fixed-Length and Run-Length Compression

This repository contains implementations of Fixed-Length and Run-Length compression and decompression algorithms, developed using CUDA.

Detailed implementation information can be found in IMPLEMENTATION-PLAN.md (note: the document is in Polish, as it was created as part of a university assignment).

Building

To build this project, refer to the CMakeLists.txt file.

Running

Run the program with the following command:

./compress operation method input_file output_file

Parameters:

• operation: Specifies whether to compress (c) or decompress (d).
• method: Selects the compression method:
  • fl: Fixed-length compression using the GPU.
  • fl-cpu: Fixed-length compression using the CPU.
  • rl: Run-length compression using the GPU.
  • rl-cpu: Run-length compression using the CPU.
• input_file: Path to the input file.
• output_file: Path to the output file (contents will be overwritten if the file already exists).

Testing

To run the tests, use the following command:

ctest
