硬件代价 meaning in Chinese

hardware cost

Comparing with other cache store miss policies , cache adaptive write allocate policy avoids unnecessary memory traffic , reduces cache pollution and decreases memory queue full rate without increasing hardware overhead
与传统的cache写失效处理策略相比, cache自适应写分配策略硬件代价小,避免了不必要的数据传输,降低cache污染,减少存储管理队列阻塞的频率。
And more aperture extension is achieved in this novel esprit - based two - dimensional angle estimatio n scheme using a uniform rectangular array of vector hydrophones spaced much farther apart than a half - wavelength . this proposed scheme and the attendant vector - hydrophone array outperform a uniform half - wavelength spaced pressure hydrophone array with the same aperture and slightly greater number of component hydrophones by an order of magnitude in estimation standard deviation
结合实际的应用情况，对矢量水听器构成的阵列进行了初步的探讨，利用本文前面部分所分析的基于单矢量水听器的方法，实现了阵元间距突破半波长上限的局限，并解决了角度估计的循环模糊问题，以较小的硬件代价和运算代价实现阵列孔径的扩展，提高估计精度。
