Abstract :
Software-defined radio (SDR) belongs to an emerging class of applications with the processing requirements of a supercomputer but the power constraints of a mobile terminal. The authors developed the signal-processing on-demand architecture (SODA), a fully programmable architecture that supports SDR, by examining two widely differing protocols, W-CDMA and 802.11A. It meets power-performance requirements by separating control and data processing and by employing ultrawide SIMD execution
