Abstract
A network interface for a workstation is configured to supply data to a host bus. A bus interface unit is configured to output the data frame onto the host bus based on a master or slave transfer request to access the buffer memory. The slave request to access the buffer memory may be in the form of either an I/O mapped or memory mapped request. A memory management unit includes request logic to receive the master and slave transfer requests and to generate a generic request to access the buffer memory. The memory management unit is configured to transfer the data frame between the buffer memory and the host bus in response to the generic request. The memory management unit effectively accesses stored data independent from the type of data transfer mode. Notably, the modes of data transfer, master or slave, can be changed within the transfer of a single frame, on a per-byte basis.
