Patent number: 9069466Abstract: Source-synchronization between a source module and a responder module generally includes providing, at the source module, an initial determinism reconciliation signal, propagating the initial determinism reconciliation signal from the source module to the responder module and back to the source module to produce a received determinism reconciliation signal, and compensating for an intrinsic delay of the circuit based on the initial determinism reconciliation signal and the received determinism reconciliation signal.Type: GrantFiled: October 15, 2012Date of Patent: June 30, 2015Assignee: ADVANCED MICRO DEVICES, INC.Inventors: Michael Tresidder, Li Sun

Patent number: 8879680Abstract: A transmitting interconnect interface inserts clock mismatch compensation symbols into a transmitted data stream so as to allow the receiving interconnect interface to compensate for clock frequency mismatch between transmit-side and receive-side clocks. The transmitting interconnect interface adjusts the rate of insertion of these symbols based on a determination of the clock frequency mismatch. The transmitting interconnect interface can incrementally adjust the insertion rate to change substantially proportionally with changes in the clock frequency mismatch. Alternatively, the transmitting interconnect interface can set the insertion rate to one of two levels. By adapting the insertion rate to the current measured clock frequency mismatch, the bandwidth penalty incurred by transmitting clock mismatch compensation symbols in excess of that necessary to permit receiver clock tolerance compensation can be reduced, thereby permitting more transmit bandwidth to be used for transmitting data.Type: GrantFiled: November 6, 2012Date of Patent: November 4, 2014Assignee: ATI Technologies ULCInventors: Michael Tresidder, Gordon F. Caruk

Patent number: 8868945Abstract: Many computing device may now include two or more graphics subsystems. The multiple graphics subsystems may have different abilities, and may, for example, consume differing amount of electrical power, with one subsystem consuming more average power than the others. The higher power consuming graphics subsystem may be coupled to the device and used instead of, or in addition to, the lower power consuming graphics subsystem, resulting in higher performance or additional capabilities, but increased overall power consumption. By transitioning from the use of the higher power consuming graphics subsystem to the lower power consuming graphics subsystem, while placing the higher power consuming graphics subsystem in a lower power consumption mode, overall power consumption is reduced.Type: GrantFiled: April 19, 2010Date of Patent: October 21, 2014Assignee: ATI Technologies ULCInventors: Sasa Marinkovic, Phil Mummah, Mingwei Chien, Michael Tresidder, Roumen Saltchev, George Xie, Jason Long

Publication number: 20080143731Abstract: Graphics generated by one graphics processor are transferred across a high speed interconnect bus to a frame buffer. The rendered frames from the frame buffer are presented on a display by way of a display interface in communication with the frame buffer. The display interface of another existing (e.g. integrated) graphics adapter/subsystem may be used to present the rendered frames on an interconnected display.Type: ApplicationFiled: November 30, 2007Publication date: June 19, 2008Inventors: Jeffrey Cheng, Terry Laviolette, James Huang, Robert Zabrzycki, Jason Long, Xiangquan Weng, Sasa Marinkovic, Phil Mummah, Mingwei Chien, Michael Tresidder, Roumen Saltchev, George Xie, Iouri Litchmanov
