DecodeX Exploring and Benchmarking of LDPC Decoding across CPU, GPU, and ASIC Platforms

This repository presents DecodeX, a unified benchmarking framework for evaluating low-density parity-check (LDPC) decoding acceleration across different hardware platforms. DecodeX integrates a comprehensive suite of LDPC decoder implementations, including kernels, APIs, and test vectors for CPUs (FlexRAN), GPUs (Aerial and Sionna-RK), and ASIC (ACC100), and can be readily extended to additional architectures and configurations.

Current supported benchmarking frameworks consists of the following:

Hardware	Implementation	Platform
CPU	FlexRAN	Intel Xeon
CPU	OAI	Intel Xeon
ASIC	DPDK-BBDev	ACC100
GPU	OAI	RTX 6000 Ada
GPU	Sionna-rk	Jetson AGX Orin
GPU	Aerial	H200
GPU	Aerial	RTX 3090
GPU	Aerial	RTX 6000 Ada
