ABSTRACT:
A transmit packet buffer device capable of asynchronous read and write functions is used for receiving frame data from a host and forwarding the data over a network. The device comprises dual-ported memory capable of independent write and read access, a plurality of registers for storing address pointers to locations in the memory, and a logic device coupled to the dual-ported memory and the plurality of registers for controlling downloading data into the memory at a first clock speed, and transmitting data from the memory at a second clock speed. The registers are used to store memory addresses for reference by the logic device, and the data is divided into frames.
