    • There is provided a method of scheduler assisted power management for semiconductor devices. By accessing and analyzing workload data for tasks to be completed, a scheduler may provide finer grained control for determining and implementing an efficient power management policy. In this manner, tasks with completion deadlines can be allocated sufficient resources without wasteful power consumption resulting from ramping up of performance through overestimating of voltage or frequency increases. Additionally, power management may be planned for longer periods, rather than looking only at immediate data to be processed and constantly fluctuating voltage and frequency. In this manner, power management can run more smoothly and efficiently compared to conventional means of power management that ignore data from a scheduler when determining power management policy.
    • 提供了一种用于半导体器件的调度器辅助电源管理的方法。 通过访问和分析要完成的任务的工作负载数据,调度器可以提供更精细的粒度控制以确定和实现有效的电力管理策略。 以这种方式,具有完成期限的任务可以被分配足够的资源,而不会由于通过过高估计电压或频率增加而提高性能而导致浪费的功率消耗。 此外,电源管理可能会计划更长的时间,而不是仅查看要处理的即时数据和不断波动的电压和频率。 以这种方式,与在确定电源管理策略时忽略来自调度器的数据的电力管理的传统手段相比,功率管理可以更平稳和有效地运行。

    • There is provided a semiconductor package configured for externally controlled power management. Instead of integrating voltage regulation on-chip as done conventionally, power regulation is moved externally to the PCB level, providing numerous package advantages including size, simplicity, power efficiency, integration flexibility, and thermal dissipation. In particular, the use of flip-chip package configurations provides ready access to power supply bumps, which also allows the use of a universal receiving PCB and power supply through simple reconfiguring of voltage traces. As a result, flexible power management can be implemented, and portions of semiconductor packages may be managed for performance or thermal considerations, which may be of particular use for applications such as multi-core processors.
    • 提供了一种配置用于外部控制电源管理的半导体封装。 功率调节不是像以往那样集成电压调节片上,而是将功率调节从外部移到PCB级,提供了许多封装优势,包括尺寸,简单性,功率效率,集成灵活性和散热。 特别地,使用倒装芯片封装配置可以方便地访问电源突点,这也允许通过简单重新配置电压迹线来使用通用接收PCB和电源。 因此,可以实现灵活的功率管理,并且可以管理半导体封装的部分以用于性能或热考虑,这可能对于诸如多核处理器的应用特别有用。
