Four types of accesses are defined using this messaging approach, namely memory read, memory write, configuration read and configuration write. The type of register access desired is defined by the appropriate value in a vendor-specific type field in the header of the vendor defined message.

Thus, more reduced headers can be transmitted over time with a resulting increased efficiency. Both sides of the PCI Express transaction must support this system and method for this approach to be enabled. Once enabled, both the PCI Express transmitter and receiver can use the regular full header PCI Express packets as well as the reduced header packets. | 01-19-2012 |

20140126612 | ADAPTIVE CLOCK MISMATCH COMPENSATION SYMBOL INSERTION IN SIGNAL TRANSMISSIONS - 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 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. | 05-08-2014 |
