摘要： The present disclosure describes programmable logic that may be operated in a turbo processing mode to cause an ongoing operation to be completed faster than a scheduled completion time. With at least some of the remaining time to the scheduled completion time, power savings may be realized by operating the programmable logic into a deep sleep mode, where configuration memory associated with the programmable logic may be set to a suitable voltage level as to not cause data loss at lower or zero voltage levels but otherwise realize power savings relative to an amount of power consumed during average processing operations.

摘要： Systems or methods of the present disclosure may provide for determining a load line for operation of a programmable logic fabric where the load line is based at least in part on design configuration details for a design or a configuration rather for generic deployment of the programmable logic device. The load line may be determined using software modeling for the design or configuration. Additionally or alternatively, the load line may be determined using runtime testing and sensing of real-world parameters. This determination based on real-world parameters of a deployment of the configuration or design is based on a determination of a step load for the design or configuration.

摘要： Systems or methods of the present disclosure may provide efficient electric power consumption of programmable logic devices based on providing different voltage levels to different portions (e.g., voltage islands) of the programmable logic device. For example, the programmable logic device may include circuitry to provide different voltage levels to different voltage islands. The programmable logic device may implement and operate logic configurations with different operating parameters using different operating voltages for efficient electric power consumption.
