Android transplantation and analysis based on Loongson

Loongson processor mainly consists of three series such as respectively and for embedded applications, mid-range and low-end desktop and low-end server applications. Android operation system transplantation based on PC104 Plus processor-based platforms as the core of China-made CPU loongson 2F. And evaluate its performance. Described the Android system framework and kernel, and make the appropriate changes for the Loongson processors, conduct test analysis of each module and the entire system. The specific migration steps include: kernel download and modify and transplantation, file system modifications and transplantation, modification and testing of some of the functional modules, integrated test. The experimental results show that real-time performance of the system can meet the demand for general industrial control systems. Android transplanted to loongson hardware platform has important industrial and practical significance to the promotion of domestic loongson series.
