并行可配置ECC专用指令协处理器

采用软硬件结合的方法，给出一种基于VLIW的并行可配置椭圆曲线密码体制（ECC）专用指令协处理器架构。该协处理器采用点加、倍点并行调度算法，功能单元微结构采用可重构的思想，具有高度灵活性与较高运算速度，能支持域宽可伸缩的GF（p）与G只2″）有限域上的可变参数Weierstrass曲线，签名认证算法可升级。实验结果表明，GF（p）域上192bit的ECC点乘运算只需0．32ms，比其他同类芯片运算速度提高了116％～350％。

Parallel and Reconfigurable ECC Application Specific Instruction-set Coprocessor

With the hardware/software co-design methodology,a parallel and reconfigurable architecture of Euiptic Curve Crypto System(ECC) application specific instruction-set coprocessor is proposed,which is based on VLIW processor techniques.The coprocessor introduces parallel ECC point addition and doubling scheduling algorithms.Based on the concept of reconfiguration,the micro-architectures of function modules are designed.The whole ECC coprocessor has the characteristics of high flexibility and high processing sp...
