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.
