摘要： Dynamic program analysis is decoupled from execution in virtual computer environments so that program analysis can be performed on a running computer program without affecting or perturbing the workload of the system on which the program is executing. Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed.

Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed. Recording and analysis are carried out on heterogeneous systems so that they can be separately optimized.

摘要： A virtual machine system decouples dynamic program analysis from program execution. Program analysis is decoupled from program execution through the use of a virtual machine to record program execution and an analysis platform to replay and analyze the program execution. Optimization techniques are applied to prevent the analysis platform from falling too far behind the program execution platform during replay.

摘要： The execution behavior of a selected application is recorded for subsequent replay. During recording, only those portions of memory that are accessed by the selected application are stored. As a result, the amount of data that is stored during the recording session is reduced and data that is not necessary for replaying the selected application, which may include possible sensitive and personal information, are not stored.
摘要翻译：记录所选应用程序的执行行为，以便后续重播。在记录期间，仅存储由所选择的应用访问的存储器部分。结果，减少了在记录会话期间存储的数据量，并且不存储可能包括可能的敏感和个人信息的重放所选择的应用所需的数据。

摘要： Replay-time-only functionalities in a computer program are executed only during replay in a virtual machine and are skipped outside of replay. If a replay-time-only functionality is detected during the replay of a program execution in a virtual machine, the replay may be paused and the virtual machine state may be saved. The replay-time-only core functionality is executed. When this execution is complete, a prior state of the virtual machine may be restored and the replay may be resumed.
摘要翻译：仅在虚拟机中重放时才执行计算机程序中的仅重播功能，并在重播之外跳过。如果在重放虚拟机中的程序执行期间检测到仅播放时间功能，则可以暂停重放并且可以保存虚拟机状态。重播时间核心功能被执行。当该执行完成时，可以恢复虚拟机的先前状态并且可以恢复重放。

摘要： An electronic circuit includes a selectively configurable differential signal interface and a selection control input for selecting one of a plurality of standard differential signal interfaces for configuration of the differential signal interface. The selection control input selects one of the following plurality of standard differential signal interfaces: reduced swing differential signaling (RSDS), low voltage differential signaling (LVDS), mini low voltage differential signaling (mini-LVDS), and bussed low voltage differential signaling (BLVDS), for configuration of the differential signal interface. The electronic circuit may also include a plurality of selectable voltage sources (611, 612, 613) and a plurality of selectable current sources (614, 615, 616, 617), for selecting, in response to an input signal at the selection control input, at least one of an operating D.C. voltage, a standard differential signal voltage, and a standard differential signal current for the differential signal interface.

摘要： A closed loop delay line system (700) includes a phase lock loop that provides a phase lock output signal (715). A delay line (702) includes a clock input, a delay line output, and a delay line bias input. A bias signal provided to the delay line bias input (727) adjusts the speed of the delay line (702). A phase detector (720) compares phase between a first timing signal input (704) and the delay line output (706). A bias adjust circuit (726) mixes the phase compare output signal (725) and the phase lock output signal (715) to provide a combination bias signal (727) to the delay line (702). Additionally, the relative timing position of strobe outputs (734) from the delay line (702) can be individually adjusted.
