Vectorized Base64 Encoding/Decoding for RISC-V RVV

This repository contains a vectorized Base64 encoding and decoding library targeting the RISC-V Vector Extension (RVV)

Project Structure

• lib/ - Contains the core library code implementing Base64 encoding and decoding using RISC-V RVV instructions.
• example/ - Contains example executable code demonstrating how to use the Base64 library.

Prerequisites

To build and run this project, you will need:

• A RISC-V cross-compiler, specifically riscv64-unknown-linux-gnu-gcc
• CMake version 3.13 or later

Building the Project

1. Clone the repository

   git clone https://github.com/vogma/base64rvv
   cd base64rvv

2. Create a build directory

   mkdir build && cd build

3. Generate build files using CMake

   cmake ..

   or

   cmake .. -DBUILD_EXAMPLE=ON

   to build an executable demonstrating encoding and decoding functionality.

4. Build the project

   cmake --build .

Cross Compilation

To cross compile this library, cmake has to be configured to use the correct cross-compiler. For example:

CC=riscv64-unknown-linux-gnu-gcc cmake ..
