Optimization of Modules for Digital Audio Processing

摘要

Today the demands of power optimized strategies have become one of the biggest challenges for developers. The sooner the aspect of low power is considered in the design process the greater the effect is on power consumption of the system design later on. Therefore the developer should have access to power information at an early stage of the design process. Our approach is to develop a design framework which allows a high level specification of a given algorithm while allowing a consistent hardware implementation of a digital signal processing system across all steps in the tool-chain, from the behavioral specification up to the placed and routed netlist. In this paper we present how to use this framework for the optimization of digital audio processing modules and show some results.
