Abstract
A method and apparatus for bridging network protocols is disclosed. In one embodiment, a data frame is received and stored in a dual-port memory queue by hardware logic. An embedded processor is notified of the data frame once a programmable number of bytes of the data frame have been received and stored. Once notified, the embedded processor may then undertake to read the data frame from the memory queue while the hardware logic is still writing to the memory queue. In one embodiment, the processor may then translate the data frame's protocol and begin transmitting it out over a network connection, all while the data frame's payload is still being received.
