非线性布尔函数实现技术研究

摘要

To improve the processing efficiency of nonline Boolean function in processor,a non-line Boolean function model was established based on extract shift and and-XOR.The model used the decimation shift operation for selecting the variables in-volved in operations,and-XOR operation was utilized to achieve different times and XOR between items.Finally,performances evaluation and adaptation functions were presented.The results showed that computational model of non-line Boolean function could significantly reduce the number of operations required by the non-line Boolean function.%为了提升处理器中非线性布尔函数处理效率，建立了以抽取移位和与-异或为基础的非线性布尔函数计算模型。利用抽取移位操作选择非线性布尔函数中参与运算的变量，利用与-异或操作实现不同次数与项之间的异或运算。对设计的单元进行了性能评估和函数适配，测试结果表明，设计的非线性布尔函数计算模型能够大幅降低实现非线性布尔函数所需的运算次数。
