The Design and Data-Throughput Performance of Readout Module Based on ZYNQ SoC

ZYNQ has gradually become a flexible and suitable architecture with field-programmable gate arrays and dual-high-performance advanced RISC machine Cortex-A9 processors in applications of data acquisition and readout systems in the field of nuclear electronics. The high data rate and high-efficient data-throughput performance between the programmable logic (PL) and processing system (PS) is essential in a readout module based on ZYNQ. In this paper, four typical readout electronics system architectures are introduced, and the details of hardware and software design of the new-generation compact readout module RAIN1000Z2 based on ZYNQ XC7Z020-CLG400 are illustrated. Then, the data-throughput performance tests between the PL and PS are designed and implemented. The highest performance readout mode can reach more than 2000 MB/s data-throughput in different high-performance port combination modes. In conclusion, recommendation of combination mode is given for different data-throughput applications' requirements in readout applications based on the ZYNQ-based readout module.
