Reconfigurable computing represents an intermediate approach between the extremes of ASIC's efficiency and general-purpose processor's flexibility, promising a valuable alternative to the multimedia processing. 可重构计算代表了介于ASIC和通用处理器之间的计算途径,为多媒体图像处理提供了一个非常有价值的发展方向。
It converts the digital intermediate frequency signal down to zero intermediate frequency signal, and lessens the signal rate to the rate which the DSP processor can handle. 它将数字中频信号下变频至零中频信号,并使信号速率降至通用DSP器件能够处理的速率。
