Abstract
A controller for providing buffering between a data source/destination and a network. The network is coupled to the controller through an Ethernet bus. The controller includes an Ethernet MAC Core coupled to the Ethernet bus. A buffer is disposed between the MAC Core and the data source/destination for storing data/control frames. Each frame has an Ethernet data portion and an Ethernet MAC Core control signal portion to reduce central processing unit overhead in processing transmission and reception of Ethernet frame data. A control section enables the frames to pass between the source/destination and the network through the MAC Core under control of the buffer stored Core control signals portion of the frame.
