摘　　要：高性能处理器(CPU)是嵌入式领域应用的关键部件之一,主要用于设备的控制及协议处理功能。现有的国产处理器平台还不具备可信功能,在CPU的BIOS启动、操作系统启动及应用层不支持可信度量功能。设计一种支持可信的国产处理器平台能够实现嵌入式领域关键部件的安全控制功能,核心部件CPU采用了国产的龙芯2H处理器。简要介绍了龙芯2H处理器,从硬件和软件设计两方面分别具体阐述了实现安全可信的设计方法,并通过示例进一步验证了平台的正确可行。The high-performance processor （CPU） is one of critical parts used in embedded application domain. It is mainly used to realize the control and protocol processing functions. The existing domestic processor platform can＇t yet support credible function, and can＇t support credible measurement function at the BIOS startup, operating system startup and application layer. A domestic processor platform supporting credible function is designed to realize security control function of critical parts in embedded domain. The key part CPU adopts the domestic loongson 2H processor. This paper briefly introduces Loongson 2H processor. The design method for security creditability is described from hardware and software. The correctness and feasibility are proved by an example.
