针对双单片机冲床主从式系统的软件分工，分别设计主CPU系统和从CPU系统的软件结构。主CPU完成系统的管理和数据处理等非实时性任务，从CPU 完成插补和位置控制等实时性任务。采用双口RAM通信协议，加速主从CPU系统间机床状态信息和加工数据的传送。

The software structures of the principal CPU and the subordinate CPU are designed respectively on software division of principal-subordination system of dual MCU punch.Non real time tasks,such as system man-agement?and data processing,are completed by the principal CPU;real time tasks are completed by the subordi-nate CPU,including interpolation and position control.Two-port RAMcommunication protocol is adopted to ac-celerate the transmission of machine tool state information and processing data between the principal CPU system and the subordination CPU system .
