A reconfigurable SoC tailored to Software Defined Radio applications

Abstract

This paper presents the mapping of SDR applications on a reconfigurable SoC, based on a run-time reconfigurable coarse-grain accelerator called CREMA. CREMA is characterized by mapping adaptiveness, meaning that its architecture is specified according to the needs of the application mapped on it. CREMA is used to accelerate two kernels used in SDR applications: correlations for synchronization purposes and FFT for the OFDM modulation/demodulation. In both cases we show that the implementation on CREMA is 4X faster that a similar implementation on a general-purpose coarse-grain accelerator, and that its resource occupation is reduced by 4.5X.
