AGGIOS products are centered around the concept of software defined energy management (SDEM). SDEM is an exciting new technology that enables innovation in how we design and manage energy, power and thermal characteristics of electronic devices. SDEM has three defining characteristics. First, SDEM abstracts higher-level platform behavior. Second, it separates the platform management plane from the processing plane. And third, SDEM consolidates the platform management plane, so that a single software platform manager controls multiple processing plane elements.

AGGIOS products support the SDEM concept with the Seed embedded software and the EnergyLab design tool with its UHA model library. The complete development cycle is covered from power simulation and trade-off analysis to run-time platform management and testing of the final product.

AGGIOS EnergyLab design tool is an integrated design environment (IDE) for the design, visualization, and test/measurement of power, energy, latency and thermal behavior of multicore SoCs, integrated platforms and complete applications. AGGIOS EnergyLab relies on the IEEE P2415 UHA standard and adapts the AGGIOS Seed embedded software to specifics of the customer hardware and software, optimizing operating characteristics such as power, energy, thermal, and latencies.

AGGIOS Unified Hardware Abstraction (UHA) is an OS-agnostic formal description format. The AGGIOS UHA model library provides descriptions for standard hardware IP, enabling rapid and accurate power modeling tailored to custom systems and applications.

The UHA abstraction describes:

• The programmer’s view of SoC and board components (processors, busses, memories, accelerators, controllers, PMICs) with their operating states and operating points annotated with power, thermal, capability, latency, constraint, retention and transition information;
• Clock trees, voltage rails, power islands, reset trees, and their hardware and software control;
• Constraints as well as inter-component dependencies;
• OS tasks, routines and applications annotated with their energy requirements;
• Outside impacts on device’s power behavior;

UHA introduces the new Scene concept which describes typical use cases and user activities conducted on the device combined with energy consumption and quality of service information. Scenes are combined and transitioned by the Seed run-time software using user defined Scene transition tables and a set of Scene combination rules.

UHA is the proper superset of the Device Tree (DTS) enumeration and driver matching abstraction widely used by the Linux and Open Firmware communities making it easy to import and export the DTS files from UHA.

AGGIOS Seed embedded software enables run-time management of power, energy, latency and thermal characteristics for heterogeneous multicore multiOS SoCs and complete applications. Seed software drivers and firmware kernel complement the standard OSes and take full control over platform management: The Seed software drivers and firmware kernel complement the standard OSes and take full control over platform management:

• Detect and respond to power management directives by the various OSes including during power transitions;
• During OS suspend periods manage the sleep, suspend and dark wake states of the device;
• Coordinate power state changes of components, clusters and subsystems;
• Manage UHA operating points and scenes required by the application;
• Execute control code to retain state information during transitions;
• Change power states by directly accessing hardware components, including clocks, PLLs and PMICs;
• Provide run-time power and energy estimates;

Seed accomplishes the above tasks and delivers:

• Fast and precise execution of power state changes;
• Optimized power states meeting performance and latency requirements;
• Small footprint to fit within local memory of dedicated cores;
• Flexibility to distribute energy management across all the participating cores and OSes as well as type 1 and type 2 hypervisors;
• Support for wide range of processors ranging from application processors to dedicated power management and always-on-cores;

Supported target devices

Optimized Seed embedded software is available for all Xilinx UltraScale+ MPSoC devices, including:

• All UltraScale+ MPSoC CG devices
• All UltraScale+ MPSoC EG devices
• All UltraScale+ MPSoC EV devices

Seed embedded software can be generated for a wide range of other architectures and devices using the EnergyLab Seed generator.
