Patents by Inventor Seok-Woo SONG

Seok-Woo SONG 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).

  • Patent number: 10585709
    Abstract: An apparatus and a job scheduling method are provided. For example, the apparatus is a multi-core processing apparatus. The apparatus and method minimize performance degradation of a core caused by sharing resources by dynamically managing a maximum number of jobs assigned to each core of the apparatus. The apparatus includes at least one core including an active cycle counting unit configured to store a number of active cycles and a stall cycle counting unit configured to store a number of stall cycles and a job scheduler configured to assign at least one job to each of the at least one core, based on the number of active cycles and the number of stall cycles. When the ratio of the number of stall cycles to a number of active cycles for a core is too great, the job scheduler assigns fewer jobs to that core to improve performance.

  • Patent number: 9405349
    Abstract: A multi-core apparatus includes cores each including an active cycle counting unit configured to store an active cycle count, and a stall cycle counting unit configured to store a stall cycle count. The multi-core apparatus further includes a job scheduler configured to determine an optimal number of cores in an active state based on state information received from each of the cores, and adjust power to maintain the optimal number of cores.
