摘　　要：为了提高可重构网络安全处理器中CPU、密码模块和网卡等各功能部件之间的数据传输效率,提出了一种链式多通道分组直接存储器存取(direct memory access,DMA)传输方式,设计了链式多通道分组DMA的硬件架构,使用65 nm CMOS工艺标准单元库对链式多通道分组DMA进行了ASIC实现并搭建了仿真验证平台,结果表明使用链式多通道DMA的可重构网络安全处理器内部通信性能明显提升.In order to improve the data transmission efficiency between the CPU,cryptographic module and network card in the reconfigurable network security processor,a chain multi-channel packet direct memory access(DMA)transmission mode was proposed.The hardware architecture of chain multi-channel DMA was designed,and the 65 nm CMOS process standard unit library was used to ASIC implement the chain multi-channel packet DMA to build a simulation verification platform.The results showed that the internal communication performance of the reconfigurable network security processor using chained multi-channel DMA was significantly improved.
