基于AHB总线的多模式低功耗DES/3DES IP核的实现

Implementation of multi mode low power DES/3DES IP core based in AHB bus

设计了一种低功耗低资源的DES/3DES加解密软核,可以兼容ECB,CBC,CFB三种模式,具有AMBA AHB总线接口,可以方便集成在一些低功耗SoC下作为加解密数据协处理模块。该软核在90nm工艺130MHz时钟频率下逻辑综合结果为8835门,通过了FPGA验证,最高吞吐量达到416Mbps,表明其为可重用的软核。

Designed a low power and low resources DES/3DES encrypt and decrypt soft IP core. It has 3 different mode： ECB, CBC, CFB and an AMBA AHB interface. It can be integrated in some low power SoC as an encrypt/decrypt co-process module. This core is synthesized under 90nm technology 130MHz clock frequency, about 8835 gates, and it＇ s verified by FPGA. ,the highest throughput is 416Mbps. So it＇ s proved to be a reused IP.
