论文摘要
低密度奇偶校验检查代码（LDPC）的近频道性能激发了其广泛的应用。随着代码大小的复杂性的增长，LDPC代码的迭代解码提供了重大的实现挑战。将芯片（MPSOC）与芯片网络（NOC）集成多处理器系统（NOC）的最新趋势为并行实现提供了模块化平台。本文提出了一个基于HEMP的LDPC代码解码的实施平台，这是基于NOC通信结构的开源MPSOC框架。最小总和算法用于解码LDPC代码，并使用HEMPS工具进行模拟。介绍了以252x504均衡矩阵为特征的1/2 LDPC代码测量的数据速率和加速因子
The near channel performance of Low Density Parity Check Codes (LDPC) has motivated its wide applications. Iterative decoding of LDPC codes provides significant implementation challenges as the complexity grows with the code size. Recent trends in integrating Multiprocessor System on Chip (MPSoC) with Network on Chip (NoC) gives a modular platform for parallel implementation. This paper presents an implementation platform for decoding LDPC codes based on HeMPS, an open source MPSoC framework based on NoC communication fabric. Reduced minimum sum algorithm is used for decoding LDPC codes and simulations are performed using HeMPS tool. The data rate and speedup factor measured for decoding a rate 1/2 LDPC code characterised by 252x504 parity matrix is presented
