为提高Tausworthe均匀随机数(TURN)的生成速度,提出了一种可快速配置、并行输出非相关TURN序列的简单生成方法。该方法利用线性反馈移位寄存器结构特点,采用优化的输出生成矩阵,可高速并行输出非相关TURN序列。在不增加寄存器等资源前提下,同时采取两组优化的输出矩阵,可生成满足应用质量要求的非相关TURN序列对,所需硬件资源仅为组合Tausworthe结构和一步多跳算法的27.4%和48.8%,该优势随输出非相关TURN序列个数的增多而更趋显著。 |

Abstract: |
To improve the generation speed of Tausworthe uniform random numbers(TURN),a fast configurable parallel output structure is proposed,which can generate uncorrelated TURN sequence at high speed using different optimized output generator matrix. More importantly,independent TURN sequence pairs can be obtained with two different optimized output matrices without adding more hardware resources. Compared with combined Tausworthe structure and multiple-bit skip-ahead algorithm,only 27.4% and 48.8% hardware resources are used,the advantages are more significant with the increase of output independent TURNs. |
