    • 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.
    • 公开了一种桥接网络协议的方法和装置。 在一个实施例中,数据帧被硬件逻辑接收并存储在双端口存储器队列中。 一旦数据帧的可编程数量的字节已经被接收和存储,嵌入式处理器就被通知数据帧。 一旦通知,当硬件逻辑仍在写入存储器队列时,嵌入式处理器然后可以承担从存储器队列读取数据帧。 在一个实施例中,处理器然后可以转换数据帧的协议,并且开始通过网络连接发送它,同时数据帧的有效载荷仍在被接收。
