DEVICE AND METHOD FOR MEDIA ACCESS CONTROL

摘要

A method for media access control, the method includes generating at least one media access grant in response to at least one media access request. The method is characterized by monitoring a data line, while maintaining at least a clock line in a low power mode, to detect at least one media access request generated by at least one component connected to the data line and to the clock line; and forcing the at least clock line to exit the low power mode and starting a contention prevention period, when the media access controller or at least one component requests to access the data line. A device including multiple components that are connected to a data line, and adapted to transmit information over the data line at a transmission rate responsive to a first clock rate. The device is characterized by further including a clock signal provider that is adapted to provide a high frequency clock signal over the data line and further adapted to determine, before a completion of the transmitting and in response to the transmitted information, when to substantially reduce the clock rate.
