The power consumption of modern System-on-Chips (SoC) is determined by the switching activity of the internal logic. This can be reduced, for instance, with clock gating methods. In this case, the clock distribution is modified such that the amount of switching is reduced.

Still, the internal state transitions may exhibit an encoding that relies on implementational constraints or readability rather than power reduction. For instance, a binary counter causes a higher power consumption than a grey-code counter where only a single bit flip per counting step is needed.

In this thesis, a method is to be developed that uses simulation data to determine the internal state sequences of a given digital circuits. On this base, an optimized coding scheme that minimizes the number of register toggles per cycle is to be designed. The method should be shown on a given design example from a current design project.

WHAT TO DO:

  • Extraction of state sequences from digital circuit simulations
  • Concept and implementation of an algorithm for determining an energy-reducing coding scheme
  • Implementation of a tool that integrates the new coding scheme into the digital circuit
  • Evaluation of the method on a design example
  • Documentation

WHAT TO BRING WITH YOU:

  • Python
  • Verilog

AND THIS IS US:

We strengthen enterprises with application-oriented research and development in microelectronics, systems engineering and mechatronics and transfer the results of basic research into applications and products. We support companies in launching internationally successful innovations for health, the environment and industry and provide solutions from the feasibility study to series production.
