Study and design of embedded trace debugging technology based on virtual technology

This paper discusses embedded trace debugging technology based on ARM11 kernel in intelligent terminal software system. For the convenient analysis on operation process control and the positioning of abnormal situations of ARM subsystem during research and development of intelligent terminal products, this paper proposes a real-time trace debugging technology program with high reliability, strong real time and comprehensive functions. The key technology of this program is to use virtual technology to integrate effectively resources of Android subsystem and ARM subsystem in intelligent terminal software system, realizing real-time trace and printing of base band operation status.
