Kenzo Van Craeynest has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Providing an asymmetric multicore processor system transparently to an operating system
    Patent number: 9720730
    Abstract: In one embodiment, the present invention includes a multicore processor with first and second groups of cores. The second group can be of a different instruction set architecture (ISA) than the first group or of the same ISA set but having different power and performance support level, and is transparent to an operating system (OS). The processor further includes a migration unit that handles migration requests for a number of different scenarios and causes a context switch to dynamically migrate a process from the second core to a first core of the first group. This dynamic hardware-based context switch can be transparent to the OS. Other embodiments are described and claimed.

  • Processor scheduling with thread performance estimation on cores of different types
    Patent number: 9286128
    Abstract: A processor is described having an out-of-order core to execute a first thread and a non-out-of-order core to execute a second thread. The processor also includes statistics collection circuitry to support calculation of the following: the first thread's performance on the out-of-order core; an estimate of the first thread's performance on the non-out-of-order core; the second thread's performance on the non-out-of-order core; an estimate of the second thread's performance on the out-of-order core.
