The traditional COMe module adopts x86 architecture (such as Intel / AMD) and foreign operating system (such as Windows Embedded), and there is a risk of supply chain security and data leakage. Although domestic processors (such as Loongson, Feiteng) and operating systems (such as Loongnix, UOS) have gradually matured, but the integration in the standardized module (such as COMe) still faces the challenges of interface adaptation, driver support and performance optimization.
