Abstract

With the ever-increasing data rates in radio astronomy, a universal Field Programmable Gate Array (FPGA)-based hardware platform which can be used at different locations in the signal processing chain, like a beamformer, data router or correlator, would reduce development time significantly. In this paper, we present the design of such a platform, the UniBoard2. With UniBoard2, both large rack-based and single-board systems can be made. Standard Quad Small Form-factor Pluggable (QSFP) input and output (IO) interfaces on the front side make it easy to interface UniBoard2 to standard 40 Gigabit Ethernet (GbE) network equipment. Hardware design challenges, like transceiver links, power supplies, power dissipation and cooling are described. The paper concludes with some examples of systems (like beamformers and correlators) that can be built using the UniBoard2 hardware platform.

一个通用的可扩展的射电天文学高性能计算平台UniBoard2

随着射电天文学数据速率的不断增长，一个基于通用现场可编程门阵列（FPGA）的硬件平台，可以在信号处理链的不同位置使用，如波束形成器、数据路由器或相关器，将大大缩短开发时间。在本文中，我们介绍了这样一个平台的设计，UniBoard2。使用UniBoard2，既可以制作基于大型机架的系统，也可以制作单板系统。前端的标准四路小型可插拔（QSFP）输入和输出（IO）接口使UniBoard2能够轻松连接到标准40千兆以太网（GbE）网络设备。描述了硬件设计的挑战，如收发器链路、电源、功耗和冷却。本文最后给出了一些可以使用UniBoard2硬件平台构建的系统（如波束形成器和相关器）的示例。

期刊介绍： The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
