The development of DFT accelerators in edge devices requires high energy efficiency due to the limited battery capacity. In this context, emerging devices such as resistive RAM (RRAM) provide a promising solution. They enable the design of high-density crossbar arrays and facilitate massively parallel and in situ computations within memory. However, the reliability and performance of the RRAM-based systems are compromised by the device non-idealities, especially when executing DFT computations that demand high precision. In this paper, we propose a novel adaptive variability-aware crossbar mapping scheme to address the computational errors caused by the device variability. To quantitatively assess the impact of variability in a communication scenario, we implemented an end-to-end simulation framework integrating the modulation and demodulation schemes. When combining the presented mapping scheme with an optimized architecture to compute DFT and inverse DFT(IDFT), compared to the state-of-the-art architecture, our simulation results demonstrate energy and area savings of up to 57 % and 18 %, respectively. Meanwhile, the DFT matrix mapping error is reduced by 83% compared to conventional mapping. In a case study involving 16-quadrature amplitude modulation (QAM), with the optimized architecture prioritizing energy efficiency, we observed a bit error rate (BER) reduction from 1.6e-2 to 7.3e-5. As for the conventional architecture, the BER is optimized from 2.9e-3 to zero.
