本文针对多输入多输出接收机设计了一种硬件节能的随机上下分解(LUD)方案。通过采用随机计算,可以用简单的逻辑门来完成lcd中复杂的算术运算。本文提出的双分区计算方法使随机乘法器和分法器具有较高的计算精度和较短的随机流长度。我们利用CMOS 130纳米技术设计并合成了随机led。根据布局后的报告,与现有的LUD方法相比,随机LUD的硬件效率高达1.5倍,当矩阵尺寸为8 × 8及以上时,其能量效率也高于目前最先进的LUD方法。
In this paper, we design a hardware and energy-efficient stochastic lower-upper decomposition (LUD) scheme for multiple-input multiple-output receivers. By employing stochastic computation, the complex arithmetic operations in LUD can be performed with simple logic gates. With proposed dual partition computation method, the stochastic multiplier and divider exhibit high computation accuracy with relative short length stochastic stream. We have designed and synthesized the stochastic LUD with CMOS 130-nm technology. According to the postlayout report, the hardware efficiency of the stochastic LUD is as high as 1.5× compared with the exiting LUD methods, and the energy efficiency is also higher than the state-of-the-art LUD when the matrix dimension is 8 × 8 and larger.
