Abstract:
Software defined radio (SDR) solutions for mobile devices
need to be energy efficient to extend battery life. At the
same time, SDR solutions need to support easy portability of
waveforms (WFs). To address these contradicting needs of
efficiency and WF-portability, a novel concept, the Nucleus
concept, has been proposed. The Nucleus concept, which is
library based, provides flexibility in implementing a WF by
making available efficient implementations for critical
components of a WF. Due to the existence of a huge design
space in mapping a WF to a hardware platform, tool
assistance is highly beneficial, if not mandatory. An
important step towards a mapping-tool is to analyze,
understand and precisely capture the requirements of a tool
in accordance with the Nucleus concept. This paper
contributes a methodology for a tool-assisted mapping and
evaluation in the Nucleus concept. Various information
sources and the information that needs to be captured by the
mapping-tool are identified. A two-level evaluation is
proposed to enable fast convergence to an ideal mapping
efficiently.
