    This paper proposes a novel hardware-based multidimensional sorting algorithm and its respective architecture, called real-time hardware sorter (RTHS), for emerging data intensive processing applications where performance and resource conservation are serious concerns. The basic idea behind RTHS is to reduce the hardware complexity of parallel hardware sorting architectures (PHSAs) through a high-performance scalable matrix-based sorting method. The proposed method can also be used for implementing Min/Max queues or finding the largest/smallest records exclusively in the big data application. Implementing the RTHS design on a Virtex-7 field-programmable gate array (FPGA) reveals that the number of lookup tables (LUTs) of the proposed method has decreased by 66.3% and 87.3% compared to the conventional Bitonic sorting network (CBSN) and the state-of-the-art PHSA, respectively. In addition, the number of required registers for the proposed method has decreased by 94.8% compared to the state-of-the-art PHSA.
