Component-based software engineering (CBSE) is an attractive solution for describing baseband processing applications. It abstracts waveforms in the traditional way algorithm designers envision their applications and guarantees a high degree of portability. However, existing CBSE approaches for SDR have not been able to close the gap between specification and implementation so as to achieve the computational performance and the energy efficiency of handcrafted solutions. Providing a methodology that closes this gap in an efficient way has been the focus of the Nucleus Concept as reported in previous publications [1,2]. This paper presents a tool flow that follows the Nucleus Concept, and thus allows for efficient component-based SDR development. Additionally, the tool flow is supported by a robust environment and integrated with state-of-the-art tools for system level design. The whole flow is demonstrated on the basis of a state-ofthe- art MIMO OFDM receiver.
