  • Publication number: 20160066724
    Abstract: Embodiments described herein relate generally to monitoring a dining session using smart smallwares. A smart smallware may sense usage or non-usage associated with a dining session of a customer. Based on the sensed non-usage of the smart smallware, the smart smallware may detect a period of inactivity. In response to the detected period of inactivity, the smart smallware may transmit an indication of the detected period of inactivity. This transmitted indication may cause an external monitoring device to notify a waitperson that a customer associated with that smart smallware may require attention. Other embodiments may be described and/or claimed.

  • Publication number: 20160006544
    Abstract: Embodiments include apparatuses, methods, and systems for jitter equalization and phase error detection. In embodiments, a communication circuit may include a data path to pass a data signal and a clock path to pass a clock signal. A jitter equalizer may be coupled with the data path and/or clock path to provide a programmable delay to the data signal and/or clock signal, respectively. The delay may be determined by a training process in which a supply voltage may be modulated by a modulation frequency. The delay may be dependent on a value of the supply voltage, such as a voltage level and/or jitter frequency component of the supply voltage. A phase error detector is also described that may be used with the communication circuit and/or other embodiments.

  • Publication number: 20150082062
    Abstract: A memory controller operable for selective memory access to areas of memory exhibiting different attributes leverages different memory capabilities that vary access speed, retention time and power consumption, among others. Different areas of memory have different attributes while remaining available to applications as a single contiguous range of addressable memory. The memory controller employs an operating mode that identifies operational priorities for a computing device, such as speed, power conservation, or efficiency. The memory controller identifies an area of memory based on an expected usage of the data stored in the area, for example an access frequency indicating future retrieval. The memory controller therefore selects areas of memory based on the operating mode and the expected usage of data to be stored in the area according to a heuristic that favors areas of memory based on those exhibiting attributes having a high correspondence to the expected usage of the data.

  • Patent number: 8547769
    Abstract: Multiple dies can be stacked in what are commonly referred to as three-dimensional modules (or “stacks”) with interconnections between the dies, resulting in an IC module with increased circuit component capacity. Such structures can result in lower parasitics for charge transport to different components throughout the various different layers. In some embodiments, the present invention provides efficient power distribution approaches for supplying power to components in the different layers. For example, voltage levels for global supply rails may be increased to reduce required current densities for a given power objective.
