Security Architecture Network Terminal Hardware Structure Design And Implementation

In order to enhance the security of network computer,a new secure architecture which called sCPU-dBUS is proposed in "Security Architecture Network Client technology".This architecture contains two system buses instead of the traditional architecture' system bus:the local bus and the network bus.Hierarchical model of embedded system based on platform-level design concepts,embedded system can be divided into five layers:physical layer,hardware abstraction layer,core layer,system layer and application layer,and a complete set of package and interface specification also is given in this model.The hardware system of the security architecture network terminal is designed and implemented in this paper.The main task is the completion of the physical layer and hardware abstraction layer's design and implementation.According to the subject requirements,identified the various parts of the hardware system.On this basis,design and build a SOPC system with single CPU and dual-bus architecture in the Altera FPGA by SOPC technology,implement the peripheral controllers' in the SOPC System and design the peripheral controllers' driver program.The design and implement of SANC's motherboard is also given at the end of paper.
