摘要
系统设计经常需要考虑FPGA、DSP及多种电源加电时序及复位管理,本文基于DSP芯片对多路电源的上电时序及复位要求,通过FPGA控制各种分散电源的上电顺序,完成DSP板上电复位。仿真结果和示波器测试结果验证了FPGA逻辑的有效性,能精确控制上电时间间隔,实现电源上电时序的控制,满足现有项目的实际需求。
In the system design,it is often necessary to consider FPGA,DSP and various power supply timing and reset management.Based on the power supply timing and reset requirements of DSP chip,the power supply sequence of various distributed power sources is controlled by FPGA to complete the power reset of DSP board.The simulation results and the oscilloscope test results verify the effectiveness of FPGA logic,which can accurately control the power time interval,realize the control of the power power time sequence,and meet the actual needs of existing projects.
