Abstract
An Ethernet controller has a host interface for coupling to a host processor and a physical layer transceiver for coupling to a data network and includes multiple data objects having different access times where the data objects communicate with the host interface over an internal data bus. The Ethernet controller includes a data object interface module coupled between the host interface and the internal data bus where the data object interface module has a first access time for handling data requests for the data objects received on the host interface from the host processor, and a control logic circuit coupled to control the operation of the data object interface module. Data requests from the host processor for accessing data stored in the multiple data objects are carried out through the data object interface module using the first access time, regardless of the different access times of the multiple data objects.
