The paper presents a new memory-addressing scheme for the realization of low power FFT processors. The scheme is based on the minimization of coefficient access and the reduction of switching activity by modifying the butterfly sequence. Therefore, power consumption in the complex multiplier and memory is significantly saved.
Network-on-Chip (NoC) based Multi-Processor System-on-Chip (MPSoC) architecture is a promising SoC design solution, offering high computational power with lots of flexibilities. However, finding the optimal MPSoC architecture configuration remains an enormous challenge due to its high structural complexity and functional diversity. In this paper, we(More)
IEEE 802.11e wireless LAN standard supports the call admission control (CAC) for the quality of service (QoS) traffic such as video and voice based on the medium time which means the bandwidth allocation normalized by the arrival time interval of corresponding traffic streams. IEEE 802.11e defines the medium time and its argument, MPDU exchange time which(More)
