  • Patent number: 11138112
    Abstract: Disclosed embodiments relate to remote atomic operations (RAO) in multi-socket systems. In one example, a method, performed by a cache control circuit of a requester socket, includes: receiving the RAO instruction from the requester CPU core, determining a home agent in a home socket for the addressed cache line, providing a request for ownership (RFO) of the addressed cache line to the home agent, waiting for the home agent to either invalidate and retrieve a latest copy of the addressed cache line from a cache, or to fetch the addressed cache line from memory, receiving an acknowledgement and the addressed cache line, executing the RAO instruction on the received cache line atomically, subsequently receiving multiple local RAO instructions to the addressed cache line from one or more requester CPU cores, and executing the multiple local RAO instructions on the received cache line independently of the home agent.

  • Patent number: 7911222
    Abstract: A method for a mix mode driver to accommodate traces of different lengths includes storing in the mix mode driver a set of one or more control signals and coefficient signals for a trace length. The one or more control signals select a number of the stages to generate a variable amplitude data output signal. Each stage is operable to increase or decrease a data signal, and each of the coefficient signals determines the magnitude of increase or decrease of the data input signal by a stage. A method for operating the mix mode driver includes generating the variable amplitude data output signal with one or more of the stages, and providing the variable amplitude data output signal to a trace.

  • Patent number: 7823003
    Abstract: An input circuit is provided for coupling to a source-synchronous multi-level bus carrying data, clock, and complementary clock signals. The clock and complementary clock signals have a less than full voltage swing than the data signal so they can act as reference voltages for the data signal. The circuit includes a first differential receiver having inputs coupled to the data and the clock signals, a second differential receiver having inputs coupled to the data signal and a reference signal, and a third differential receiver having inputs coupled to the data and the complementary clock signals. The circuit further includes first, second, and third flip-flops having data inputs coupled to outputs of the first, the second, and the third differential receivers, and clock inputs coupled to a delayed clock signal generated from the clock and the complementary clock signals. The outputs of the flip-flops determine the level of the data signal.

  • Patent number: 7802153
    Abstract: A method is provided to align clock and data signals over a source-synchronous link. The method includes sending header data and a default clock signal over the link. The header indicates a start of a training packet and the default clock signal ensures that the header is received without error. The method further includes providing a long clock pulse, phase shifting the clock signal during the long clock pulse, and thereafter sending training data and the clock signal over the link. The above steps are repeated until the training data are received with error. At that point, the phase shift of the clock signal is saved as a boundary of an optimal alignment. The above steps are then repeated with the clock signal shifted in a different direction. Once another boundary is located, the boundary midpoint is saved as the phase shift that provides the optimal alignment.

  • Patent number: 7622945
    Abstract: A method for a mix mode driver to accommodate traces of different lengths includes sequentially shifting values of a data signal to a number of stages and sequentially amplifying the values of the data signal at least one stage. Depending on the length of trace for the data signal, the method further includes providing at least one amplifying coefficient to at least one stage and coupling a subset of the stages to an adder. The method finally includes outputting the data signal from the adder to the trace.
