    摘要： When content, such as premium video or audio, is decoded, the content is stored in protected memory segments. Read access to the protected memory segments from a component not in a frame buffer protected (FBP) mode is blocked by a memory controller. The memory controller also blocks components in the FBP mode from writing to unprotected memory segments. The content may be processed by a processing engine operating in the FBP mode and may only be written back to protected memory segments. The memory segment may later be marked as unprotected if the memory segment is no longer needed. If the content is encrypted in protected memory, the encrypting key associated with the memory segment may be removed. If the content is stored in the clear, the protected memory segments are scrubbed before releasing the segments for use as unprotected memory segments.

    摘要翻译： 当诸如高级视频或音频的内容被解码时，内容被存储在受保护的存储器段中。 从不在帧缓冲区保护（FBP）模式的组件读取受保护的存储器段的访问被存储器控制器阻止。 存储器控制器还阻止FBP模式中的组件写入不受保护的存储器段。 内容可以由在FBP模式下操作的处理引擎来处理，并且可以仅被写回到受保护的存储器段。 如果不再需要存储器段，则存储器段可以稍后被标记为不受保护。 如果内容在受保护的存储器中被加密，则可以去除与存储器段相关联的加密密钥。 如果内容以清晰的方式存储，则在释放用作无保护内存段的段之前，将对受保护的内存段进行擦除。

    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： 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.

    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.
