Abstract

The Joint Test Action Group (JTAG) protocol is a popular method to program field-programmable gate array (FPGA) devices where a more intelligent technology is not applicable. However, the original JTAG protocol is designed for a short-distance connection and is not necessarily suitable when the FPGA device is located in a remote radiation area. We developed a custom optical transmission technique for the JTAG protocol. A small receiver test board is developed based on discrete devices, and a multiport distributor is implemented on an FPGA board. We also developed a technique to overcome the latency due to serialization and cable length. We present the evaluation results and future applications.

辐射环境下光纤多端口远程JTAG

联合测试行动组（JTAG）协议是一种流行的现场可编程门阵列（FPGA）设备编程方法，在这种情况下，更智能的技术是不适用的。然而，最初的JTAG协议是为短距离连接而设计的，当FPGA设备位于远程辐射区域时并不一定适用。我们为JTAG协议开发了一种定制的光传输技术。开发了基于离散器件的小型接收机测试板，并在FPGA板上实现了多端口分配器。我们还开发了一种技术来克服由于串行化和电缆长度造成的延迟。我们介绍了评估结果和未来的应用。

期刊介绍： The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years. The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
