An ever-increasing number of appliances incorporate Ethernet connectivity. With the popularity

of the Internet, IP protocol connectivity is required in many applications. In this application

note we present a functional structure for an Ethernet driver and a mini IP/UDP stack thatcan be incorporated in any Internet appliance. This driver structure is flexible to allow for hardwarechanges (changing the Ethernet chip) with minimal code changes. We suggest someimplementation constructs using DSP/BIOS kernel objects. We also highlight the advantagesof using the DSP/BIOS objects to solve certain problems as opposed to a structure without an operating system.
