The core of the coprocessor is the modular arithmetic units array for parallel computing, while a single modular arithmetic unit is composed of a high-performance scalable Montgomery modualr multiplication unit and a high-performance scalable modular addition and subtraction unit. 该协处理器的核心为并行计算的模算术单元阵列,每个模算术单元由一个高性能可扩展的Montgomery模乘单元和一个高性能可扩展的模加减单元组成。
