IEEE is forming the IEEE P2415 Unified Hardware Abstraction and Layer Working Group and IEEE P2416 Power Modeling Meta-standard Working Group. Both will draft standards that are intended to support development of more powerful and economically affordable electronics.
“Mobile and wall-powered consumer devices continue to put stringent demand on battery performance, energy consumption and heat dissipation, which requires systems to implement many complex power-aware operational modes,” says Stan Krolikoski, chair of the IEEE Computer Society’s Design Automation Standards Committee, which is sponsoring both working groups. A year-long study group of more than 30 active participants resulted in these two new standards projects.
The proposed IEEE P2415 “Standard Project for Unified Hardware Abstraction and Layer for Energy Proportional Electronic Systems” is intended to define the syntax and semantics for energy-oriented description of hardware, software and power management for complete electronic systems. It will enable specifying, modeling, verifying, designing, managing, testing and measuring the energy features of an electronic device, covering both the pre- and post-silicon design flow.
On the hardware side, the description will address enumeration of on- and off-chip components, memory map, bus structure, interrupt logic, clock and reset tree, operating states and points, state transitions, energy and power attributes. On the software side, the description will address software activities and events, scenarios, external influences and operational constraints, and, on the power-management side, the description will address activity-dependent energy control.
The new standard, once completed and approved, will be intended to be compatible with the current IEEE 1801-2013 (UPF) standard to support an integrated design flow. Additionally, the new standard would complement functional models in standard hardware description languages IEEE 1076 (VHDL)2, IEEE 1364 (Verilog)3, IEEE 1800 (SystemVerilog)4 and IEEE 1666 (SystemC)5, by providing an abstraction of the design hierarchy and an abstraction of the design behavior with regard to power and energy usage.
The IEEE P2416 “Standard Project for Power Modeling to Enable System Level Analysis” is being created to propose a meta-standard focused on parameterization and abstraction, enabling system, software and hardware IP-centric power analysis and optimization. This standard, once completed and approved, will define the required concepts and semantics for the development of parameterized, accurate, efficient and complete power models for systems and hardware IP blocks usable for system power analysis and optimization. These concepts include process, voltage and temperature (PVT) independence, power and thermal management interface, workload and architecture parameterization. Resulting models will be suitable for use in both software-development and hardware-design flows, as well as in representing both pre-silicon estimated and post-silicon measured data.
Both working groups are seeking participants for the development of these standards. For more information on the IEEE P2415 working group, visit this site. For more information on the IEEE P2416 working group, visit this site.
