通常认证卡的速度受限于板卡CPU的总线宽度及MIPS和认证算法的速度 .随着认证算法采用FPGA高速硬件实现 ,以CPU为核心的认证卡设计思想已不能满足速度需求 .提出了一种基于FPGAPS配置的在线可编程、速度不依赖于CPU的高速认证PCI卡的设计方案 .该方案已被实现 ,其思想具有通用性 ,可广泛地应用于数据加密、图像处理等高速PCI卡设计 .
Usually the speed of the authentication card is limited by the bus width of the CPU and the speed of the MIPS and authentication algorithm.As the authentication algorithm is implemented by FPGA high-speed hardware, the design idea of the authentication card with CPU as the core can not meet the speed requirement. Based on FPGAPS configuration of online programmable, speed-independent CPU-based high-speed certification PCI card design.This scheme has been achieved, the idea has versatility, can be widely used in data encryption, image processing and other high-speed PCI card design .
