About the project

The TOLOP project comprises investigations into three of the levels necessary for a paradigm shift in low-power electronics:

  • Fabrication and measurement of devices which are inherently low-power in switching operation at room temperature
  • Theory of specific device implementations for each of those technologies to explain and validate the principles behind their low-power capabilities
  • Design of architecture to enable the circuit operation of these technologies for overall low-power circuit operation

In each case there will be an investigation of the inherent losses at realistic switching rates, and estimations of the device-circuit-operation trade-offs for minimising energy consumption. Metrics such as the energy-delay product will be provided for each implementation and benchmarked against existing commercial and research technologies.

Project Goals

  1. Novel single-atom, single-electron and spintronic devices will be investigated experimentally. In the first two cases, the structures are inherently CMOS-compatible whilst in the third a higher-risk approach will be taken whilst still addressing manufacturability
  2. Both non-Boolean implementations such as multi-valued logic and parallel logic, and optimised Boolean logic implementations will be addressed. Non Boolean logic has the potential for exponential improvement in power needs
  3. Architectures and operating protocols will be designed to optimise the total power consumption of a circuit-level implementation, taking into account measured and estimated losses at realistic operating rates and temperatures

Device-level proof of concept will be achieved experimentally, driving the design of specific implementations, with theoretical investigation of viability in a realistic circuit environment.

About the 7th Framework Program

Knowledge lies at the heart of the European Union's Lisbon Strategy to become the “most dynamic competitive knowledge-based economy in the world”. The ‘knowledge triangle’ – research, education and innovation – is a core factor in European efforts to meet the ambitious Lisbon goals. Numerous programmes, initiatives and support measures are carried out at EU level in support of knowledge.

The Seventh Framework Programme (FP7) bundles all research-related EU initiatives together under a common roof playing a crucial role in reaching the goals of growth, competitiveness and employment; along with a new Competitiveness and Innovation Framework Programme (CIP), Education and Training programmes, and Structural and Cohesion Funds for regional convergence and competitiveness. It is also a key pillar for the European Research Area (ERA).
