摘　　要：提出了一种可编程安全处理器PSP(Programm ab le Security Processor)的体系结构,该体系结构由SPARC V8处理器内核、AHB片上总线及密码算法模块等部分构成,密码算法模块通过AHB总线与处理器内核进行高速交互.FPGA原型实现表明,该安全处理器能通过SPARC指令编程进行灵活控制,密码算法模块可以按需配置,能够满足嵌入式计算中对安全性和灵活性的需要.A programmable security processor （PSP） architecture was proposed to satisfy the need of security and flexibility in embedded computing. The architecture was mainly consisted of a SPARC V8 CPU core, AHB on chip bus and cryptography module. The cryptography module can exchange data with the CPU core at high speed through AHB bus. The FPGA prototype implementation shows that the security processor constructed with this architecture can be controlled by SPARC instruction programming. The cryptography module can be configured flexibly.
