The AST2500 is famous for its high-performance and Video Engine . From the datasheet:
SOL (Serial over LAN) for accessing command-line interfaces. Aspeed Ast2500 Datasheet
According to the datasheet, the AST2500 supports a 2D graphics engine capable of supporting high resolutions. This allows the BMC to provide a remote KVM (Keyboard, Video, Mouse) experience that feels local to the user. The AST2500 is famous for its high-performance and
A defining characteristic of a BMC is its ability to "talk" to the main host CPU. The dedicates significant space to the Low Pin Count (LPC) and Enhanced Serial Peripheral Interface (eSPI) bus specifications. Aspeed Ast2500 Datasheet
