| Abstract: | To meet requirements of signal processing of transition-edge sensor (TES) readout system, for field programmable gate array (FPGA) signal processing mode, signal simulation is conducted based on graphics-processing-unit (GPU), compute-unified-device-architecture (CUDA) and other platforms．Signal processing mode of combined FPGA and GPU is applied to signal readout and processing of TES, simplifying complexity of algorithm execution and improving flexibility of signal processing system．The feasibility to apply this processing mode to primordial gravitational waves detection experiment in Ali, Tibet, China was verified． |
