Patent number: 8626966Abstract: Systems and methods and computer program products are disclosed to determine the source data rate even in cases where the sink device is not directly coupled to the source device. A method includes, forming a logical channel from a source device to a sink device where the logical channel is configured to carry the source data stream and one or more rate parameters. The rate parameters relate a data rate of the source data stream to a data rate of the logical channel. Another method includes, detecting a logical channel in a received data stream where the logical channel includes the source data stream, recovering one or more rate parameters from the received data stream, determining a data rate of the logical channel, and determining the data rate of the source data stream based on the data rate of the logical channel and the one or more rate parameters.Type: GrantFiled: March 23, 2012Date of Patent: January 7, 2014Assignee: ATI Technologies ULCInventors: Nicholas J. Chorney, Collis Q. Carter

Patent number: 8589770Abstract: Control symbols taking the form {k1-k2-k2-k1} are inserted in a serial stream including m bit data words. k1 and k2 are each predefined m bit control words differing from the m bit data words. The Hamming distance between k1 and k2 is at least 2. Such control symbols may be robustly detected in the presence of a one bit error in the symbol, or a data word immediately preceding or following the symbol. The m bit words may be 8B/10B encoded data, or defined control words. The control symbols may be used for data delineation, stream synchronizaiton, transmitter/receiver synchronization or for other control signalling.Type: GrantFiled: February 26, 2008Date of Patent: November 19, 2013Assignee: ATI Technologies ULCInventors: Collis Q. Carter, Nicholas J. Chorney, James R. Goodman

Patent number: 8161204Abstract: Systems and methods for synchronizing a source and sink device are disclosed. A sink device can efficiently determine the source data rate even in cases where the sink device is not directly coupled to the source device. A method for transmitting a source data stream from a source device to a sink device includes, forming a logical channel from a source device to a sink device, where the logical channel is configured to carry the source data stream, and one or more rate parameters. The rate parameters relate a data rate of the source data stream to a data rate of the logical channel.Type: GrantFiled: April 12, 2010Date of Patent: April 17, 2012Assignee: ATI Technologies ULCInventors: Nicholas J.
