  • Publication number: 20170269666
    Abstract: Techniques for managing components of a processing system are described. Illustrative components include graphics processing units (GPUs), central processing units (CPUs), communication fabrics, memory controllers, or peripheral control circuits. For one embodiment, a performance control logic/module obtains information associated with components of a system during performance of a task by the system. The logic/module can determine the need to adjust an operational performance of a first component based on the obtained information. The performance control logic/module can also evaluate the obtained information to determine that the operational performance of one or more second components of the system should be adjusted to satisfy the determined need (of the first component). Moreover, the logic/module can adjust a first clock signal affecting the operational performance of the first component and one or more second clock signals affecting the operational performance of the one or more second components.
