Latest Patents

Xekalakis holds a patent for the "Dynamic reconfiguration of a multi-core processor to a unified core." This invention describes a method where a first thread is executed in a first pipeline of a first core of an integrated circuit (IC). The first core includes a first set of hardware structures, while a second thread is executed in a second pipeline of a second core of the IC, which includes a second set of hardware structures. In response to a command to operate the IC with a unified core, the first core is combined with the second core to obtain the unified core. The unification process involves merging the first pipeline with the second pipeline to create a unified pipeline, as well as combining the first and second sets of hardware structures to form a unified set. Ultimately, a single thread is executed in the unified pipeline of the unified core using the unified set of hardware structures. This patent showcases his innovative thinking and technical expertise in processor design.
