Abstract: Based on the analysis of architecture of android and Loongson-based platform, some key techniques of porting Android system are studied. The Android source code has been modified according to the architecture and property of Loongson, then an Android Gingerbread system for Loongson-based is implemented. The performance of the optimized Dalvik virtual machine of the system is tested and verified. This work is valuable to other Android version transplant to Loongson-based platform.
