Constructing variability maps by correlating off-state leakage emission images to layout information
Patent number: 8131056Abstract: Improved techniques are disclosed for monitoring or sensing process variations in integrated circuit designs. Such techniques provide such improvements by constructing variability maps correlating leakage emission images to layout information. By way of example, a method for monitoring one or more manufacturing process variations associated with a device under test (e.g., integrated circuit) comprises the following steps. An emission image representing an energy emission associated with a leakage current of the device under test is obtained. The emission image is correlated with a layout of the device under test to form a cross emission image. Common structures on the cross emission image are selected and identified as regions of interest. One or more variability measures (e.g., figures of merit) are calculated based on the energy emissions associated with the regions of interest.Type: GrantFiled: September 30, 2008Date of Patent: March 6, 2012Assignee: International Business Machines CorporationInventors: Stanislav Polonsky, Peilin Song, Franco Stellari, Alan J.

Patent number: 8126078Abstract: A method and apparatus are disclosed for reducing noise, such as external noise, cross-talk and echo, in an unbalanced channel. A cross-talk canceller is disclosed that uses a multi-dimensional finite impulse response filter to process both the differential, d, and common-mode, c, components of a received signal. Recovery of the differential mode component of the received signal is improved by reducing the contribution of the common mode component. The common mode component of a received signal may be expressed, for example, as the average of two voltages or two current signals. The differential and common mode components of the received signal are equalized. The disclosed multi-dimensional cross-talk canceller reduces external noise; near-end crosstalk resulting from differential and common mode components on one twisted pair interfering with another twisted pair; and echo crosstalk resulting from differential and common mode cross-talk components on the same twisted pair.Type: GrantFiled: June 30, 2003Date of Patent: February 28, 2012Assignee: Agere Systems Inc.Inventor: Kameran Azadet

Patent number: 8126940Abstract: The present invention provides techniques that allow concurrent collection of cyclic garbage on reference counting systems. In general, candidate objects are found that may be part of cyclic garbage. Each candidate object has a reference count. Two tests are performed to determine if concurrent operations have affected the reference counts of the candidate objects. If concurrent operations have not affected the reference counts, the candidate objects are collected as garbage. Additionally, during garbage collection, the decrements to reference counts are delayed so that increments occur before decrements and so that decrements are held a predetermined time before being applied. This prevents decrementing a reference and collecting a cycle as garbage right before a reference is added to an object in the cycle.Type: GrantFiled: May 29, 2008Date of Patent: February 28, 2012Assignee: International Business Machines CorporationInventors: David Francis Bacon, Vadakkedathu Thomas Rajan

Patent number: 8126262Abstract: Each video segment in a plurality of video segments is annotated with an indicator of the likelihood that the respective video segment shows a particular feature. The plurality of video segments forms an episode of interest from a given video domain. Initial feature probabilities are calculated for respective ones of the plurality of video segments using a machine learning algorithm. Each initial feature probability indicates the likelihood that its respective video segment shows the particular feature. Refined feature probabilities are determined for respective ones of the plurality of video segments by finding the most probable state sequence in a finite state machine. This is accomplished at least in part using the determined initial feature probabilities. Finally, each of the video segments in the plurality of vides segments is annotated with its respective refined feature probability.Type: GrantFiled: June 18, 2007Date of Patent: February 28, 2012Assignee: International Business Machines CorporationInventor: John R.
