摘要
MPC8250采取了基于硬件的中断现场保护机制,系统中断响应时间与所采用操作系统相关性较小。对MPC8250中断资源的合理分配并采取合适的Linux中断处理策略设计中断服务程序对提高系统的性能将有重要的意义。
The hardware context switch mechanism was adopted by MPC8250. It makes interrupt responding time of MPC8250 has less relativity with operation system. The following aspects have significant effects on system performances： assignation MPC8250 interrupt source and design interrupt service routine with reason.
