Abstract: PURPOSE: An interface device and method for high-speed physical layer transmission suitable for a wireless LAN(Local Area Network) is provided to quickly and efficiently perform an interface with a wireless physical layer by composing a multiple transmission and receipt queue classified according to a transmission rate and processing data through N addressing using a module with a circular buffer type. CONSTITUTION: A demultiplexer(611) classifies inputted data into a plurality of packets according to a transmission rate and inputs the classified data to each transmission circular buffer(613a-613c) according to the control of a transmission buffer controller by the transmission rate. A multiplexer(612) transmits the data stored in each transmission circular buffer(613a-613c) to a wireless physical layer(200) according to the control of the transmission buffer controller. The transmission buffer controller controls the demultiplexer(611) and the multiplexer(612). A demultiplexer(621) classifies the data inputted through the wireless physical layer(200) into a plurality of packets according to the transmission rate, and inputs the classified data to each receipt circular buffer(623a-633c) according to the control of a receipt buffer controller(620) by the transmission rate. A multiplexer(622) transmits the data stored in each receipt circular buffer(623a-633c) to an MAC(Medium Access Control) controller(300) according to the control of the receipt buffer controller(620). The receipt buffer controller(620) controls the demultiplexer(621) and the multiplexer(622).
