    • This disclosure addresses systems and methods for the protection of proprietary information by monitoring operational watermarks of an apparatus. A monitoring device may receive logical or physical watermark data from a defended apparatus. Watermark data may include any operational or environmental variable related to the defended apparatus. The monitoring device may maintain a baseline profile for the defended apparatus that includes watermark data. During monitoring of the defended apparatus by the monitor device, changes in the watermark data may be analyzed to determine if the baseline should be dynamically updated, or if the change indicates an anomaly. Anomalies may indicate an attempt to tamper with the defended apparatus. In response to the change that indicates an anomaly, the monitoring device may scrub the contents of the defended apparatus. In an embodiment, the monitoring device may also scrub its own memory in response to an anomaly.
    • 本公开涉及通过监视设备的操作水印来保护专有信息的系统和方法。 监控设备可以从防御设备接收逻辑或物理水印数据。 水印数据可以包括与防御装置相关的任何操作或环境变量。 监控设备可以维护包括水印数据的防御设备的基线简档。 在通过监视装置监视防御装置时,可以分析水印数据的变化,以确定基线是否应被动态地更新,或者改变是否指示异常。 异常可能表示试图篡改被篡改的设备。 响应于指示异常的变化,监视设备可以擦洗被防御设备的内容。 在一个实施例中,监视设备还可以响应于异常来擦洗其自己的存储器。

    • A method and hardware design is disclosed for allowing the bring-up of a large scale system of interfaces that need to undergo a sequence of calibration steps. The method involves the use of a flexible broadcast scheme whereby groups of interfaces within a chip are assigned to groups to which commands can be broadcast. The scheme allows for the maximum amount of flexibility, allowing interfaces to be assigned to multiple groups which can overlap and be subsets of one another, and still allows for groups to be excluded from broadcast commands and be access individually. A method is also disclosed for using a chip-global status summary that can be accessed as any other register on the chip and can report calibration results for an entire chip with only one command. According to the invention a service utilizing the method embodied with code for implementing the method can now be provided.
    • 公开了用于允许需要经历一系列校准步骤的大规模系统的接口的方法和硬件设计。 该方法涉及使用灵活广播方案,由此将芯片内的接口组分配给可以广播命令的组。 该方案允许最大的灵活性,允许将接口分配给可以重叠并且彼此子集的多个组,并且仍然允许将组排除在广播命令之外并且被单独访问。 还公开了一种用于使用芯片全局状态概要的方法,其可以作为芯片上的任何其他寄存器访问,并且可以仅用一个命令报告整个芯片的校准结果。 根据本发明,现在可以提供利用具有用于实现该方法的代码体现的方法的服务。
