Analyzing the scalability of SIMD for the next generation software defined radio
Previous studies have shown that wireless DSP algorithms exhibit high levels of data level parallelism (DLP). Commercial and research work in the field of software defined radio (SDR) has produced designs utilizing single-instruction multiple-data (SIMD) execution units to exploit this high level of parallelism. These designs have been able to deliver the efficiency and computational power needed to process 3G wireless technologies. Though efficient 3G processing has been achieved, next generation 4G SDR technology requires 10-1000x more computational performance but limits the power budget increase to 2-5x. In this paper, we present a breakdown of 4G and analyze the scalability of SIMD to see if it can help to meet the 4G requirement. We take a proposed SDR architecture, SODA, and modify it for different widths in order to calculate its efficiency. We consider the trade-offs with respect to computation and energy efficiency.
