To address the demands for high-speed and high-precision data acquisition and calibration of Cherenkov light signals generated by SiPM(Silicon Photomultiplier) arrays in LACT (Large Array of Imaging Atmospheric Cherenkov Telescopes) cameras

this study designs a high-speed multi-channel data acquisition and calibration system based on ZYNQ. The FPGA's parallel processing capabilities enable rapid signal acquisition control

real-time calibration algorithms

and multi-channel synchronization coordination. A 250Mbps(mega samples per second) high-speed ADC(analog-to-digital converter) converts optoelectronic signals to digital format

while the system coordinates with LACT's main data link through high-speed interfaces like AXI-Stream for real-time calibration data storage and feedback. Experimental verification demonstrates that the system achieves dual-channel synchronized calibration with less than 0.1% error

ensuring consistent precision in LACT's gamma-ray detection across the 1TeV-1PeV energy range. The system exhibits strong real-time performance

high stability

and excellent adaptability.
