Abstract
Described herein are various embodiments of reducing dynamic power consumption within a processor device. One embodiment provides a technique for dynamic link width reduction based on throughput demand for client of an interconnect fabric. One embodiment provides for a parallel processor comprising an interconnect fabric including a dynamically configurable bus widths and frequencies.
Claims20
A parallel processor comprising:
- a first processing cluster including a first interface node having dynamically configurable bus widths and a dynamically configurable bus frequency;
- and
- an interconnect fabric coupled with the first interface node of the first processing cluster, the interconnect fabric including circuitry to dynamically configure active bus widths for connections to the first interface node and dynamically configure the bus frequency for the connections to the first interface node, the active bus widths and the bus frequency dynamically configured based on a rate of data transfer requests through the first interface node and an efficiency comparison between an adjustment of the active bus widths and an adjustment of the bus frequency.
A method comprising:
- dynamically configuring bus widths and a bus frequency for a first interface node associated with a first processing cluster of a parallel processor;
- and
- dynamically configuring active bus widths and the bus frequency for connections to the first interface node through an interconnect fabric coupled with the first interface node, the active bus widths and the bus frequency dynamically configured based on a rate of data transfer requests through the first interface node and an efficiency comparison between an adjustment of the active bus widths and an adjustment of the bus frequency.
