J-PARC的相干Muon到电子跃迁(彗星)实验旨在寻找无中微子的Muon到电子的跃迁。我们研制了一块用于彗星秸秆管跟踪仪的读出电子板，称为稻草管仪读出电子板(Roesti)。我们计划将Roesti安装在探测器的气体歧管中。由于空间和成本的限制，真空引线的数量需要减少。为了大幅减少真空馈线的数量，我们为Roesti上的现场可编程门阵列(现场可编程门阵列)开发了一种具有菊花链功能的千兆以太网网络处理器。我们在网络处理器中实现了两个SiTCP，它们是基于硬件的千兆位以太网的TCP处理器。我们还添加了处理以太网帧和事件数据的数据路径控制器。网络处理器使Roesti能够处理对UDP/IP的缓慢控制，并通过TCP/IP传输事件数据。通过使用网络处理器，我们测量了2到6个ROESTI的吞吐量、稳定性和数据丢失率。在任意数量的单板上，事件数据传输的吞吐量稳定地达到了千兆以太网上的TCP的理论极限，Roesti稳定地发送了100%的数据。
The COherent Muon to Electron Transition (COMET) experiment at J-PARC aims to search for the neutrinoless transition of a muon to an electron. We have developed the readout electronics board called readout electronics for straw tube instrument (ROESTI) for the COMET straw tube tracker. We plan to install the ROESTI in the gas manifold of the detector. The number of vacuum feedthroughs needs to be reduced due to space constraints and cost limitations. In order to decrease the number of vacuum feedthroughs drastically, we developed a network processor with a daisy-chain function of Gigabit Ethernet for the field-programmable gate array (FPGA) on the ROESTI. We implemented two SiTCPs, which are hardware-based TCP processors for Gigabit Ethernet, in the network processor. We also added the data path controllers that handle the Ethernet frames and the event data. The network processor enables ROESTI to process the slow control over UDP/IP and to transfer event data over TCP/IP. By using the network processor, we measured the throughput, the stability, and the data loss rate for two-to-six ROESTIs. In any number of boards, the throughput of the event data transfer achieved the theoretical limit of TCP over the Gigabit Ethernet stably and ROESTI stably sent 100% of the data.
