摘要
论述了在LTE系统中基于ARM11内核的嵌入式跟踪调试技术。为了满足LTE系统中高速数据业务的需求,方便产品开发期间ARM子系统的运行流程控制和异常情况的定位分析,提出了一种可靠性高、性能强的实时跟踪调试技术方案。该方案的难点在于跟踪信息片内缓存的管理和嵌入式操作系统中高低优先级任务切换时跟踪信息的缓存处理方法,保证LTE系统的高速率运行和跟踪信息的时序性。
The embedded tracking debuging technology based on ARMI 1 core in LTE system is discussed. In order to meet the needs of high-speed data services in UI＇E system and facilitate process controlling and the location of abnormal situation analysis in the operation of ARM subsystem during the product development period, a solution of trace debuging technology is put forward, which has high reliability, strong performance and real-time property. The difficulty is how to manage on-chip cache of trace information and how to process cache of trace information when the high priority task interrupt low priority task in the embedded operating systems, in order to ensure the efficient operation of system and the timing of the trace information.
