The present invention relates to a method for efficiently performing hierarchical design rules checks (DRC) and layout versus schematic comparison (LVS) on layout areas of an integrated circuit where cells overlap or where a cell and local geometry overlap. With the present invention, a hierarchical tree describes the integrated circuit's layout data including cells having parent-child relationships and including local geometry. The present invention performs efficient layout verification by performing LVS and DRC checking on the new portions of an integrated circuit design and layout areas containing overlapping cells. When instances of cells overlap, the present invention determines the overlap area using predefined data structures that divide each cell into an array of spatial bins. Each bin of a parent is examined to determine if two or more cell instances reside therein or if a cell instance and local geometry reside therein. Once overlap is detected, the areas of the layout data corresponding to the overlap areas are selectively flattened prior to proceeding to DRC and LVS processing. During selective flattening of the overlap areas, the hierarchical tree is traversed from the top cell down through intermediate nodes to the leaf nodes. Each time geometry data is located during the traversal, it is pushes directly to the top cell without being stored in intermediate locations. This provides an effective mechanism for selective flattening.

The system comprises receiving a first image data set representative of a portion of the colon in a prone position and a second image data set representative of a portion of the colon in a supine position, at a series of viewpoints. At each of the viewpoints, an image is generated of the colon in the prone and supine positions. The prone and supine images of the colon are simultaneously displayed on a screen display in a dual view mode.

An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller (102) designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter (101) creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator (103) creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer (104) converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

When a telephone a belonging to an office a calls up a telephone b belonging to an office b, a subscriber of the telephone a operates a WS a connected to a computer network and edits camp-on request information when the telephone b is busy. The camp-on request information is transferred from the WS a to a CTI server b belonging to the office b connected to the computer network. The CTI server unit b performs camp-on control between the telephone b belonging to the office b and the telephone a belonging to the office a by controlling a private branch exchange b based on a schedule corresponding to the received camp-on request information.

Methods and apparatus for implementing memory efficient LDPC decodes are described. In accordance with the invention message information is stored in a compressed state for check node processing operations. The state for a check node is fully updated and then subject to an extraction process to generate check node to variable node messages. The signs of messages received from variable nodes may be stored by the check node processor module of the invention for use in message extraction. The check node processor can process messages in variable node order thereby allowing the variable node processor and check node processor to operate on messages in the same order reducing or eliminating the need to buffer and/or reorder messages passed between check nodes and variable nodes. Graph structures which allow check node processing on one graph iteration to proceed before the previous graph iteration has been completed are also described.

Method and apparatus for barrier synchronization of threads, for example work-stealing threads. Embodiments may provide a consensus barrier synchronization mechanism that allows a “stop world” operation being performed by two or more worker threads configured to “steal” work from other threads to complete, even if one or more of the threads are not scheduled/started by the thread scheduler and thus do not rendezvous or “check in” at a consensus barrier in a timely manner. In embodiments, portions (subtasks) of the overall task which were assigned to the tardy thread may have been completed by other work-stealing threads, and one of the other threads may check in the tardy thread at the consensus barrier upon determining that the thread is dormant and does not have any more apportioned work to be performed. In one embodiment, the task being performed may be garbage collection for a process.

Hashing functions have many practical applications in data storage and retrieval. Perfect hashing functions are extremely difficult to find, especially if the data set is large and without large-scale structure. There are great rewards for finding good hashing functions, considering the savings in computational time such functions provide, and much effort has been expended in this search. This in mind, we present a strong competitive evolutionary method to locate efficient hashing functions for specific data sets by sampling and evolving from the set of polynomials over the ring of integers mod n. We find favorable results that seem to indicate the power and usefulness of evolutionary methods in this search. Polynomials thus generated are found to have consistently better collision frequencies than other hashing methods. This results in a reduction in average number of array probes per data element hashed by a factor of two. Presented herein is an evolutionary algorithm to locate efficient hashing functions for specific data sets. Polynomials are used to investigate and evaluate various evolutionary strategies. Populations of random polynomials are generated, and then selection and mutation serve to eliminate unfit polynomials. The results are favorable and indicate the power and usefulness of evolutionary methods in hashing. The average number of collisions using the algorithm presented herein is about one-half of the number of collisions using other hashing methods. Efficient methods of data storage and retrieval are essential to today's information economy. Despite the cur-rent obstacles to creating efficient hashing functions, hashing is widely used due to its efficient data access. This study investigates the feasibility of overcoming such obstacles through the application of Darwin's ideas by modeling the basic principles of biological evolution in a computer. Polynomials over Zn are the evolutionary units and it is believed that competition and selection based on performance would locate polynomials that make efficient hashing functions.
