Abstract
A network interface device includes a random access memory used as a transmit and receive buffer for transmission and reception of data frames between a host computer bus and a packet switched network. The network interface device includes read and write controllers for each of the transmit and receive buffers, where each write controller operates in a clock domain separate from the corresponding read controller. The read and write controllers output status information corresponding to the reading or writing of a stored data frame in the receive buffer. The memory management unit includes a synchronization circuit, which arbitrates updates to the holding registers by the read and write controllers based on the asynchronously determined presence of at least one stored data frame.
