The Latency/Power Tradeoff Problem There is currently no commonly used standard to manage system power in heterogeneous multiprocessor systems. Each vendor must reinvent APIs and protocols to handle power management and spend time integrating these APIs into each codebase for every processing core in the system. To meet market windows, vendors tend to leverage existing power management solutions in the software they use for each core and then loosely couple these cores together to create ad hoc power-management regimes. These ad hoc regimes tend to have high latency power-state transitions. To work around this, companies create static, infrequently updated data-driven approaches, trading off latency for power. Because of these tradeoffs, vendors have to leave power on the table.
New Power API for Heterogeneous Processors A solution to this problem is to create an API specification that all software vendors can reasonably implement, a spec that acts as an underlying power management substrate...

AGGIOS Seed Energy Manager Provides software-Defined Power Management for Xilinx Zynq UltraScale+ MPSoC
Yesterday, AGGIOS announced its Seed Energy Manager, which provides software-defined power management for the Xilinx Zynq UltraScale+ MPSoC. I saw this new power-management tool in action yesterday at ARM TechCon in Silicon Valley. In conjunction with the company’s EnergyLab energy management synthesis tool, Seed Energy Manager gives you remarkably simple control over the power consumption of complex, multi-processor systems based on the Zynq MPSoC.

Why your set-top box is a power hog and how to increase time between charges in mobile devices; where to find some huge power savings.

Energy-efficient product design, for both portable and plug-load devices, leads the list of on-going engineering priorities. While mobile device makers have been forced by consumers' insatiable mobility requirements and fierce competition to significantly improve battery life, fixed-power products have been slower to deliver better energy consumption characteristics. But a combination of government mandates, rising energy costs, facility limitations, and a general movement to all things green makes energy efficiency a top-level concern for every type of electronics maker.
