| 摘 要： | 现有的中央处理器(Central Processing Unit,CPU)只有指令执行功能,存在安全机制不健全等问题。为防止CPU遭到恶意代码的攻击,提出一种对CPU预提交的指令逻辑进行控制的安全CPU架构设计。通过在CPU的取指、译码、调度、发射、执行、提交、ICache、发射队列IQ、ROB和内存接口等阶段对其指令和操作数进行监控,对CPU每条指令进行控制,实现信息安全机制下沉,从而发现并阻止恶意指令,防范恶意代码,提升计算机的信息安全保障能力。

| Abstract: | In view of the fact that the existing CPU(Central Processing Unit)only undertakes the instruction execution function and has not adequate security mechanism,the secure CPU architecture to prevent malicious code attack is proposed.Each instruction and the operands are under control through CPU fetch,decode,schedule,transmit,execute,commit,ICache,transmit queue IQ,ROB,to memory interface.The information security mechanism sinking is realized so that malicious instructions can be detected and prevented from executing. |
