摘要 提出了嵌入式Linux在TD-SCDMA智能手机上的实现架构,对Linux的实时性进行改进,构建了一个包含实时内核和标准内核的双内核Linux,实现事件优先级、抢占调度以及细粒度时钟。在一款TD-SCDMA无线终端评估板上进行测试,最大任务调度延时和中断响应时间分别为14 s和3 s,达到了实时性要求。 The architecture of implementing embedded Linux on TD-SCDMA smart phone is proposed. Then the design of real-time Linux is illustrated in detail, which is composed of real-time kernel and standard Linux kernel, support event priority and preempted real time, and precise time. Test on a TD-SCDMA wireless terminal evaluation board, the delay of real-time task is lower than 14μs and the interrupt response time is lower than 3μs, the need of real-time system is meet.
