A parallel signal simulator suitable for aircraft flight test is designed,which matches the general collector used in aircraft flight test. The simulator adopts P87C51 as the MCU,and dual port RAM as the interactive media bettwen the MCU and the general collector. USB 2.0 high?speed transmission interface is adopted for the communication of upper computer,which meets the requirements of real?time control and data uploading and improves the data transmission rate. The paper discusses the dual port RAM address space allocation and data sharing conflict.
