Abstract: The enhancer BRing of the High Intensity heavy-ion Accelerator Facility (HIAF) is a high-current fast-cycling synchrotron. Its beam position measurement system BPM (Beam Position Monitor)is used for investigating beam instability and beam feedback effect in addition to measuring beam trajectory and closing orbit by circle and cluster. Through detailed beam structure analysis and real-time manipulation, the system achieves low beam loss, high-efficiency transport and acceleration, ultimately meeting high-power beam design requirements. BRing BPM Electronics is developed based on ZYNQ UltraScale+ MPSoC platform. Conventional data transmission mode cannot meet the transmission requirements of BRing BPM real-time big data from logic PL part to processor PS. Therefore, a General high-speed real-time Data Transfer System AXI GRDTS (AXI General Realtime Data Transfer System) is proposed and developed. Based on ZYNQ UltraScale+ MPSoC hardware platform and 64-bit ARM Cortex-A53 embedded system on chip, a high-speed, multi-channel, universal interface data transmission IP firmware and interrupt response data processing mechanism of processor PS are designed. This system provides four high-performance (HP) data transfer ports, two ports for high-speed raw 250 MHz sampling data, up to 8 16-bit 250-MSPS ADC data transmission, the other two channels for turn-by-turn beam-by-bundle trajectory and closed-track data transmission. The bit width of each channel is 512-bit, the maximum operating frequency is 20 MHz, and the data throughput rate reaches 1280MB/s. Both laboratory and online beam tests show that the AXI GRDTS system can fulfill the design requirements of BPM real-time high-speed multi-channel data transmission, and it can be used as a universal transmission system in any electronics system based on ZYNQ UltraScale+ MPSoC.
