| Abstract: | This article discussed the embedded tracking debuging technology based on ARM11 core in LTE system. In order to meet the needs of high-speed data services in LTE system and facilitate process controlling and the location of the abnormal situation analysis in the operation of ARM subsystem during the product development period , This paper put forward a solution of trace debuging technology,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 |
