在这封信中,我们提出了一个基于图形处理单元(GPU)的LDPC卷积码(LDPC-CC)流水线解码器与优化的并行性。建议的解码器利用不同粒度的解码并行计算统一设备架构(CUDA)内核执行阶段和数据传输阶段。此外,解码器实现的参数选择标准的设计,以避免穷举搜索的所有参数的组合。实验在Nvidia GTX 460和GTX 580平台上进行。结果表明,该解码器实现了约3倍的加速比现有的基于GPU的工作。
In this letter, we present a graphics processing unit (GPU)-based LDPC convolutional code (LDPC-CC) pipeline decoder with optimized parallelism. The proposed decoder exploits different granularities of decoding parallelism for both the compute unified device architecture (CUDA) kernel execution stage and the data transfer stage. Moreover, the parameter selection criteria for decoder implementation are designed to avoid exhaustive search of all the combinations of parameters. The experiments are carried out on Nvidia GTX460 and GTX580 platforms. The results demonstrate the proposed decoder achieves about 3 times speedup compared to the existing GPU-based work.
