Abstract
This paper introduces a framework for low power co-design and optimization based on a library of pre-modeled components. The used library is enhanced with a set of features to make its use more efficient for automated co-design of real-time embedded systems. The library contains components of different architectures and types to make benefit of power-performance tradeoffs. The modeled components range from simple components to a more complex ones and IPs (Intellectual property). The modeled software components includes the instruction-level power model for selected processors and a set of optimized library routines widely used in selected areas such as in DSP. The co-synthesis process is performed based on an evolutionary algorithm for multi-objective design space exploration. To make the best utilization of the library features, the co-synthesis process is enhanced by an allocation/binding refinement step. This extra step allows trade off between performance and power. It refines the allocation/binding such that the required performance is satisfied without extra unnecessary power loss. Experiments are conducted to demonstrate the applicability of our approach using a set of benchmarks, part of them is taken from real-life examples.
