部分并行的蒙哥马利模乘法器实现研究

通讯技术的高速发展需要更高性能的密码处理设备.本文系统的研究了利用部分并行的脉动阵列结构实现模乘法器的问题,在分析了各类结构的性能结果的基础上,找到性能最高的和性能-代价比最高的结构配置.结果表明,如果以关键路径延迟×单元面积作为时间-面积代价指标,那么每个运算单元处理一位数据的设计,在0.18 μ m工艺和0.25 μ m工艺条件下,具有最高的运算性能,同时也是性价比最高的设计之一.

Implementation Study of Partly Parallel Montgomery Modular Multiplier

The rapid advance in communication technology brings a request for cryptography systems of higher performance.We systematically implement and compare several variants of partly parallel systolic architecture for Montgomery multiplier with different bit length as well as with different micro architectural approaches.The optimal options are chosen to take advantage of the underlying technology.The result analysis shows that the fully serial systolic architecture,in which one cell processes one bit,achieves the best performance.When the resource overhead is represented as area-time product,it is one of the most cost-efficient designs as well.
