Latest Patents

One of Pak-Ching Lee's latest patents is titled "Method and apparatus for using a shared ring buffer to provide thread synchronization in a multi-core processor system." This invention provides an apparatus and method for improving synchronization between threads in a multi-core processor system. The apparatus includes a memory, a first processor core, and a second processor core. The memory contains a shared ring buffer for storing data units and a plurality of shared variables associated with accessing the shared ring buffer. The first processor core runs a first thread and has a first cache associated with it, which stores a first set of local variables. The first thread controls the insertion of data items into the shared ring buffer using shared variables and local variables. The second processor core runs a second thread and has a second cache, which stores a second set of local variables. The second thread controls the extraction of data items from the shared ring buffer using shared variables and local variables.

Another significant patent is "Scalable methods for detecting significant traffic patterns in a data network." This invention provides methods and apparatuses for detecting traffic patterns in a data network. A sequential hashing scheme is utilized that includes multiple hash arrays. Each hash array contains independent hash tables with buckets that track traffic totals. As traffic is received, the totals are updated, allowing for the identification of high traffic buckets that can be used to detect significant traffic patterns in the network.
