Title:
DEVICE AND METHOD FOR MEDIA ACCESS CONTROL
Document Type and Number:
WIPO Patent Application WO2006131143
Kind Code:
A8
Abstract:
A method (100) for media access control, the method includes generating (180) at least one media access grant in response to at least one media access request. The method is characterized by monitoring (130) 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 (140) 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 (400) including multiple components (420) that are connected to a data line (430), and adapted to transmit information over the data line at a transmission rate responsive to a first clock rate. The device (400) is characterized by further including a clock signal provider (415) 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.
