摘要： The present invention, generally speaking, provides a placement method for the physical design of integrated circuits in which natural topological feature clusters (topo-clusters) are discovered and exploited during the placement process. Initial placement and placement refinement may be performed hierarchically using topocluster trees. A topocluster tree may be used to drive initial placement. An iterative placement refinement process then follows, using a technique referred to herein as Geometrically-Bounded FM (GBFM). In GBFM, FM is applied on a local basis to windows encompassing some number of bins. From iteration to iteration, windows may shift position and vary in size. When a region bounded by a window meets a specified cost threshold in terms of a specified cost function, that region does not participate. The cost function takes account of actual physical metrics-delay, area, congestion, power, etc. During placement refinement using GBFM, cluster size is adjusted iteratively from large to small as determined by horizontal cuts within the topocluster tree. GBFM occurs in the context of recursive quadrisection. Hence, after GBFM has been completed, a further quadrisection step is performed in which each bin is divided into four bins, with a quarter of the gates of the original bin being placed in the center of each of the resulting bins. GBFM then follows, and the cycle repeats until each bin contains a fairly small number of gates. Topocluster trees may also be used for quadrisection. Following the foregoing global placement process, the circuit is then ready for detailed placement in which cells are assigned to placement rows.
摘要翻译：本发明一般地提供了一种用于集成电路的物理设计的放置方法，其中在放置过程中发现和利用了自然拓扑特征簇（地形簇）。初始放置和放置细化可以使用顶簇树进行分层执行。可以使用顶层树来驱动初始放置。然后，使用本文称为几何有界FM（GBFM）的技术，随后进行迭代放置细化过程。在GBFM中，FM在本地基础上应用于包含一些数量的分区的窗口。从迭代到迭代，窗口可能会改变位置并且大小变化。当由窗口界定的区域在指定的成本函数方面满足指定的成本阈值时，该区域不参与。成本函数考虑了实际的物理量度 - 延迟，区域，拥塞，功率等。在使用GBFM进行布局优化时，通过顶层树中的水平切割确定了簇大小从大到小的迭代调整。 GBFM发生在递归四分法的上下文中。因此，在GBFM完成之后，执行进一步的四分法步骤，其中每个仓分为四个仓，原始仓的四分之一的门被放置在每个结果仓的中心。然后遵循GBFM，循环重复，直到每个仓包含相当少数量的门。群集树也可用于四次检验。按照上述全局放置过程，电路准备好进行详细的放置，其中将单元格分配给放置行。

摘要： The disclosure describes a placement method for the physical design of integrated circuits in which natural topological feature clusters are discovered and exploited during the placement process is disclosed. Topo-clusters drive initial placement, with all of the gates of a topo-cluster being placed initially in a single bin of the placement layout or within a group of positionally-related bins. An iterative placement refinement process is done using a technique referred to as Dual Geometrically-Bounded FM (GBFM). GBFM is applied on a local basis to windows encompassing a number of bins. From iteration to iteration, windows may shift position and vary in size. When a region bounded by a window meets a specified cost threshold in terms of a specified cost function, that region stops participating. Following the foregoing global placement process the circuit is then ready for detailed placement in which cells are assigned to placement rows.

摘要： Congestive heart failure (CHF) is a leading cause of death in the United States. WANDA is a wireless health project that leverages sensor technology and wireless communication to monitor the health status of patients with CHF. The first pilot study of WANDA showed the system's effectiveness for patients with CHF. However, WANDA experienced a considerable amount of missing data due to system misuse, nonuse, and failure. Missing data is highly undesirable as automated alarms may fail to notify healthcare professionals of potentially dangerous patient conditions. Embodiments of the present disclosure may utilize machine learning techniques including projection adjustment by contribution estimation regression (PACE), Bayesian methods, and voting feature interval (VFI) algorithms to predict both non-binomial and binomial data. The experimental results show that the aforementioned algorithms are superior to other methods with high accuracy and recall.

摘要： A sensor system and method configured to take multiple channels of sensors, and based on context and user behavior reflected in the signals, identifies specified channels for sensing according to a sensing policy. The sensing policy is used to reduce the amount of data sampled, such that it is possible to reconstruct the values of the non sampled sensors efficiently. The sensing policy is influenced by user and system's behavior and can be assigned either offline or in real time.
