Software Radio and Dynamic Reconfiguration on a DSP/FPGA platform

Abstract

This paper discusses the implementation of modulation chains for multi-standard communications on a dynamically and partially reconfigurable heterogeneous platform. Implementation results highlight the benefit of considering a DSP/FPGA platform instead of a multi-DSP platform since the FPGA supports efficiently intensive computation components, which reduces the DSP load. Furthermore, partial dynamic reconfiguration increases the overall performance as compared to total dynamic reconfiguration since there is 45% of bitstream size reduction, which leads to a 45% decrease of the whole reconfiguration time. The implementation of modulation chains for multi-standard communications proves the availability of new technology to support efficiently Software Defined Radio.
