Abstract: A system for debugging software uses a portable debug environment-independent client debugger object and at least one non-portable server debugger object with platform-specific debugging logic. The client debugger object has a graphic user interface which allows a user to control and manipulate the server debugger object with debug environment-independent debug requests. The server debugger object performs a platform-specific debug operation on the software to be debugged. The platform-specific results generated by the debugging operation are translated to debug environment-independent results and returned to the client debugger object. This operation allows the same client debugger object to be used with one or more server debugger objects running on different platforms.

Abstract translation: 用于调试软件的系统使用与便携式调试环境无关的客户端调试器对象和至少一个具有平台特定调试逻辑的非便携式服务器调试器对象。 客户机调试器对象具有图形用户界面，允许用户使用调试环境无关的调试请求来控制和操作服务器调试器对象。 服务器调试器对象对要调试的软件执行平台特定的调试操作。 由调试操作生成的平台特定结果被转换为调试与环境无关的结果，并返回给客户端调试器对象。 此操作允许与在不同平台上运行的一个或多个服务器调试器对象一起使用相同的客户端调试器对象。

Abstract: A set top box or like device utilizing virtualization techniques to isolate secure device resources from an untrusted software framework incorporated in the device. In one implementation, a first virtual machine container is provided for secure execution of a traditional set top box application, while a second virtual machine container is utilized to host a software framework or untrusted portions of a software framework. A secure access client/server interface is provided to support interactions between the first and second virtual machine containers. The software framework may comprise, for example, an Android framework supported by an underlying Linux operating system environment and isolated in a Linux resource container. Virtual container constructs in various embodiments may employ varying levels of hardware sandboxing, including use of dedicated processing resources in multi-processor environments. In further embodiments, the software framework may be partitioned into trusted and untrusted portions that are executed in separate virtual containers.
