摘要： A hardware-based aperture compression system permits addressing large memory spaces via a limited bus aperture. Streams are assigned dynamic base addresses (BAR) that are maintained in registers on sources and destinations. Requests for addresses lying between BAR and BAR plus the size of the bus aperture are sent with BAR subtracted off by the source and added back by the destination. Requests for addresses outside that range are handled by transmitting a new, adjusted BAR before sending the address request.

摘要： A method, system, and computer program product are provided for adjusting write timing in a memory device based on results of an error detection function. For instance, the method can include determining a write timing window between a signal on a data bus and a write clock signal based on the results of the error detection function. The method can also include adjusting a phase difference between the signal on the data bus and the write clock signal based on the write timing window. The memory device can recover data on the data bus based on the adjusted phase difference.

摘要： Techniques are disclosed relating to data inversion encoding. In one embodiment, an apparatus includes an interface circuit. The interface circuit is configured to perform first and second data bursts that include respective pluralities of data transmissions encoded using an inversion coding scheme. In such an embodiment, the initial data transmission of the second data burst is encoded using the final data transmission of the first data burst. In some embodiments, the first and second data bursts correspond to successive write operations or successive read operations to a memory module from a memory PHY.

摘要： A method, system, and computer program product are provided for adjusting write timing in a memory device based on a training signal. For instance, the method can include configuring the memory device in a training mode of operation. The method can also include determining a write timing window between a signal on a data bus and a write clock signal based on the training signal. Further, the method includes adjusting a phase difference between the signal on the data bus and the write clock signal based on the write timing window. The memory device can recover data on the data bus based on the adjusted phase difference.

摘要： Embodiments described herein include a method and system for synchronizing clocks between coupled integrated circuits (ICs) in a computer system. According to an embodiment, a dedicated timing pin is provided on a first IC. The first IC configures a second IC to change a pin assignment, so that the second IC interprets a signal sent on the timing pin by the first IC and received on the reassigned pin as a request to transmit a return signal. The return signal is received on the timing pin. The return signal is used to determine whether timing should be adjusted by the first IC. In an embodiment a clock and data recover (CDR) circuit compares the signal sent to the signal received in order to make the determination. In an embodiment the first IC is a processor-based device, and the second IC is a memory device controlled by the first device.
