Abstract: In the high-energy experiments, especially for those with high luminosity collider, the data acquisition system is designed to be capable of handling large event rate and data size. Electronics devices with Application Specific Integrated Circuit (ASIC) and Field-Programmable-Gate-Array (FPGA) are essential to perform real-time processing on the data from particle detectors. We will introduce different kinds of applications of FPGA devices in the field of experimental high-energy physics in this report. The Front-End Electronics performs Analog-To-Digital transformation on the detector raw data, where the ADC is usually based on customized ASIC design dedicated to the sensor for particle detection, and FPGA collects and transfers the data to downstream. The readout system is featured with large I/O bandwidth and memory in order to collects and buffers the data from multiple detectors for event building. The trigger systems perform complicated particle reconstruction algorithms, such as charged particle tracking, calorimeter clustering, event topology, timing determination, etc, within limited latency. We will give an overview of the data chain of DAQ, the design of each component, and the prospect of future upgrade in this field.
