A fixed-point DSP architecture for software-defined radio
Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2009.
Due to ever evolving wireless communication standards and technologies, the need for more flexible radio terminals are becoming more sought after in order to adapt to these new standards. Software-defined radio offers a solution to this demand. Software-defined radio is a radio communication system where signal processing components that have typically been implemented in hardware are replaced by reconfigurable and re-useable software modules running on a digital processor. The need exists to rapidly create new SDR applications without designing an entire system from the ground up, and without specialised knowledge of the target platform. This thesis initially describes the design of a generic SDR architecture that is highly reconfigurable and promotes a high level of code re-use. The research forms part of a larger project to design a domain-specific language (DSL) in which to describe SDR functionality in a platform-independent way. In this thesis, the code synthesis from the DSL is extended to support the Freescale DSP563xx family.
