The multi\u2010mode processor is developed by an eight\u2010parallel mixed\u2010radix architecture to efficiently produce full reconfigurability for all multi\u2010user combinations. The proposed design not only supports the operation of IFFT\/FFT for 1\u20138 different data streams operated by different users in case of downlink transmission, but also, it provides different throughput rates to meet IEEE 802.11ac requirements at the minimum possible clock frequency. Moreover, less power is needed in our design compared with traditional software approach. The design is carefully optimized to operate by the minimum wordlengths that fulfill the performance and complexity specifications. The processor is designed and implemented on Xilinx Vertix\u20105 field programmable gate array technology. Although the maximum clock frequency is 377.84\u00a0MHz, the processor is clocked by the operating sampling rate to further reduce the power consumption. At the operation clock rate of 160\u00a0MHz, our proposed processor can calculate 512\u2010point FFT with up to eight independent data sequences within 3.2~\u03bc<jats:italic>s<\/jats:italic>meeting IEEE 802.11ac standard requirements.
