Abstract: Various embodiments are generally directed to an apparatus, method and other techniques to determine whether a target address of a register for an execution instruction is valid or invalid based on a comparison between the target address and one or more valid target addresses stored in a storage, increase a number of invalid target addresses if the target address is invalid, and determine whether the number of invalid target addresses is greater than an invalid target address threshold. Various embodiments may also include initiating a security measure to prevent a security breach if the number of invalid target addresses is greater than the invalid target address threshold or executing the execution instruction if the number of invalid target addresses is less than or equal to the invalid target address threshold.

Abstract: A processor and method are described for managing different privilege levels associated with different types of program code, including binary translation program code. For example, one embodiment of a method comprises entering into one of a plurality of privilege modes responsive to detecting the execution of a corresponding one of a plurality of different types of program code including native executable program code, translated executable program code, and binary translation program code. In one embodiment, the binary translation program code includes sub-components each of which are associated with a different privilege level for improved security.

Abstract translation: 描述了处理器和方法，用于管理与不同类型的程序代码相关联的不同特权级别，包括二进制翻译程序代码。 例如，方法的一个实施例包括响应于检测到多个不同类型的程序代码中的相应的一个程序代码的执行，包括本机可执行程序代码，翻译的可执行程序代码和二进制转换，来进入多个特权模式之一 程序代码。 在一个实施例中，二进制翻译程序代码包括子组件，每个子组件与不同的权限级别相关联，以提高安全性。
