  • Patent number: 10831969
    Abstract: An integrated circuit physical design tool includes an interconnection congestion predictor that generates a congestion table for an integrated circuit design. Interconnection congestion hotspots are identified based on the congestion table. The proximity of interconnection congestion hotspots to each other is determined, and penalization values are computed based on the proximity of interconnection congestion hotspots to each other. The congestion table is then updated to reflect the penalization values due to proximity of interconnection congestion hotspots. Routability of the interconnection congestion hotspots is then predicted based on the updated congestion table. The updated congestion table may also be used by multiple physical design optimization tools, including placement, global routing, and detail routing.

  • Patent number: 10831023
    Abstract: According to one embodiment, a computer-implemented method for using a variable perceived distance viewing system includes outputting, by a computer, an image to a display visible via a variable-focus converging lens array. The variable-focus converging lens array sets a focal distance to a first perceived distance whereby the image is perceived as being present at the first perceived distance. Furthermore, the computer-implemented method includes adjusting, by the computer, the variable-focus converging lens array for adjusting a focal distance to a second perceived distance and scaling, by the computer, the image on the display to compensate for the focal distance adjustment. The features in the image at the first perceived distance have substantially the same dimensions as the same features in the image at the second perceived distance.

  • Patent number: 10802882
    Abstract: A method accelerates memory access in a network using thread progress based arbitration. A memory controller identifies a prioritized thread from multiple threads in an application. The prioritized thread reaches a synchronization barrier after the other threads due to the thread encountering more events than the other threads before reaching the barrier, where the events are from a group consisting of instruction executions, cache misses, and load/store operations in a core. The memory controller detects a cache miss by the prioritized thread during execution of the prioritized thread after the barrier is reached by the multiple threads. The memory controller then retrieves and returns data from the memory that cures the cache miss for the prioritized thread before retrieving data that cures cache misses for the other threads by applying thread progress based arbitration in the network.
