  • Patent number: 11188534
    Abstract: This application describes a data stream processing system for receiving and processing multiple data streams using a stream join model and based on the stream join model having a threshold function for which an output of the stream join model crosses the threshold two or less times (e.g., where the threshold function is a convex function, linear function, monotonic function, or other function having a similar property). The data stream processing system may generate filtered data streams using a number of techniques and algorithms without risk of false negatives and mis2169sing instances where an output of a stream join exceeds or violates a threshold condition. The data stream processing system can significantly reduce processing expense, particularly in cases where one or more devices have limited memory and where caching tuples from incoming data streams consumes significant processing resources.

  • Publication number: 20020124230
    Abstract: Timing of a global network of a circuit design is processed globally while modifications to the global network are associated with logical blocks of the circuit design. Accordingly, the global network can be divided at boundaries of the logical blocks after timing is optimized globally. Paths with the worst timing problems are processed first, and devices of the path which the largest delays are processed first. Improvements in a path's timing are achieved by replacing overloaded devices with bigger ones and/or by inserting buffers. Path segments though un-routed soft blocks are estimated by determining a density center of driven devices, determining a distance to the density center, and adding distances from the density center to each of the driven devices. Devices are categorized according to delays corresponding to driven capacitances. For each device delays are calculated and mapped for various driven capacitances and adjusted for the physical size of each device.
