Research on Adaptive Trapezoidal Shaping Algorithm Based on FPGA

摘要: 梯形成形算法是整形滤波算法中应用最广的。目前的梯形成形技术只能手动调节成形参数，操作复杂且效率低下，为了进一步增强数字脉冲幅度分析技术的便利性，增加成形算法关键参数的自适应算法。先根据原有算法原理在MATLAB SIMULINK中进行初步仿真，采用现场可编程逻辑器件(Field Programmable Gate Array, FPGA)和硬件描述语言(Verilog)完成梯形成形算法的自适应算法，利用Quartus II编写程序，并用ModelSim软件对设计进行功能仿真。通过仿真验证，结果证明设计能够自适应调整梯形成形参数，填补了数字化脉冲幅度分析技术中梯形成形算法的自适应内容。

Abstract: Trapezoidal shaping algorithm is the most widely used shape filter algorithm. The current trapezoidal shaping technology can only manually adjust the shaping parameters, which is complicated and inefficient. Enhance the convenience of digital pulse amplitude analysis technology and increase the adaptive algorithm of key parameters of the shaping algorithm. First, carry out preliminary simulation in MATLAB SIMULINK according to the original algorithm principle, use field programmable logic device (Field Programmable Gate Array, FPGA) and hardware description language (Verilog) to complete the adaptive algorithm of trapezoidal shaping algorithm, use Quartus II to write the program, and use ModelSim software to design the design perform power simulation. Through simulation verification, the results show that the design can adjust the trapezoidal shaping parameters adaptively, which fills the adaptive content of the trapezoidal shaping algorithm in the digital pulse amplitude analysis technology.
