摘　　要：MPC8270处理器以其良好的性能和丰富的接口在航空机弹载嵌入式领域有广泛的应用。MPC8270提供丰富的异常机制供软件开发者使用,由于MCP的产生与硬件有紧密关系,并不会由于软件本身导致,因此往往软件开发者对其并不在意。结合在实际工作中碰到的故障事例,对MCP进行了详细的描述。对MCP正确的处理可以增加软件的可靠性。MPC8270 processor has a wide range of applications in the field of airborne embedded system with its good performance and rich interface. MPC8270 provides a wealth of exception mechanisms for software developers to use. Because the MCP has a close relationship with the hardware,and will not be caused by the software itself,so software developers don＇t care about it. Combined with the fault cases encountered in practical work,this paper describes the MCP in detail. And the correct processing of MCP can increase the reliability of the software.
