Abstract

为满足多波束接收机、焦面阵和天线阵等超大数据量终端的处理需求,采用以GPU并行运算为处理核心的FPGA+CPU+GPU混合架构对天文相关器进行设计,利用严格时序的FPGA进行采样和预处理,基于统一计算设备架构平台开发实现GPU并行运算信号处理与CPU逻辑控制、存储和显示。测试结果表明,该相关器运行稳定、准确,通过调节混频、滤波和傅里叶变换参数即可实现通带范围内任意频带的高精度测量。

Other Abstract

In order to meet the needs of huge data processing due to the multi-beam receiver, focal plane array and antenna array, a widely used astronomical correlator is designed using FPGA + CPU + GPU heterogeneous architecture based on the kernel of GPU parallel computing. It uses a strict timing FPGA for sampling and pre-processing, a parallel computing GPU for signal processing and a CPU for logic control, data storage and display. The latters two are developed on the platform of CUDA. Test results show that the stability and reliability of this correlator are very good. It can realize high precision measurement in any band within the passband by adjusting the parameters of mixing, filting and Fourier transform.
