【Abstract】 In order to meet the needs of pixel detector data processing,a data processor is designed.The processor uses high-speed floating point calculations to meet most of the commonly used data calculation requirements,and the customized hardware calculation unit can greatly shorten the calculation time.Customize the instruction set and compiler,and use the compiler to share part of the processor’s hardware functions to simplify hardware design.FPGA prototype verification is compared with the results of computer calculations by processing ten sets of data.The average calculation error is 0.001 3 % and the root mean square error is 4.15%.Test results show that the processor can process data in real time,reduce the amount of data transmitted,simplify front-end electronics,and adapt to different application requirements.更多还原
