Abstract: In a method and apparatus for data transmission suitable for a high-performance wireless LAN, the apparatus utilizes a serial communication interface device to perform data transmission between a master and a slave. The data transmission apparatus includes a data input unit for receiving at least one of transmission rate data and transmission length data to be transmitted from the master to the slave. A selection unit receives the at least one of the transmission rate data and the transmission length data from the data input unit, and receives at least one of a corresponding first event signal and a second event signal for selectively transmitting at least one of the transmission rate data and the transmission length data respectively to the slave.

Abstract: A bus arbitration system includes a bus master, a bus arbitration circuit and a clock signal changing circuit. The bus master is configured to enter a power saving mode of operation in response to a disabled first master clock signal. The bus arbitration circuit is configured to issue a bus access grant to the first bus master in response to a request for bus access issued by the first bus master. The clock signal changing circuit is electrically coupled to the first bus master and the bus arbitration circuit. The clock signal changing circuit is configured to generate the disabled first master clock signal in response to the request for bus access. The clock signal changing circuit is further configured to convert the disabled first master clock signal to an enabled first master clock signal in response to the bus access grant.
