摘要
信号模拟系统在设备测试、数据处理等领域都有重要的意义;为了解决设备测试对多通道同步信号的需求,提出了一种基于ARM和FPGA的多通道信号模拟系统设计方法,主要介绍了以FPGA为核心的模拟输出控制模块,其中采用ARM进行多任务管理,用FPGA实现时序转换和控制,FPGA的控制逻辑采用VHDL和原理图相结合的方法设计,使用FPGA提高了系统性能并简化了外围电路设计,最后给出了模拟系统的实验结果,整个设计系统可模拟输出多路0.01Hz^40MHz的任意信号,说明了这种设计方案的有效性。
Signal Simulator is of great importance for facility testing,signal processing and other field.In order to achieve the demand of multi-channel synchronous signal for facility testing,a design method of Multi-channel Signal Simulator based on FPGA and ARM is presented,and the control modules of analog output implemented in FPGA are introduced in detail.ARM is mainly used for tasks management and states supervision.FPGA is mainly used for timing conversion and control.Control logic in the circuit design of FPGA combing VHDL with principle chart.The use of FPGA improves the system＇s performance and simplifies design of the peripheral circuits.Experiment results demonstrate that the new design approach for electrical signal simulator is valid.
