    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: A differential input circuit with lower power consumption and noise is disclosed. Rather than completely discharging output nodes differential circuits, the present invention equalizes the output nodes to conserver power and to reduce noise. Specifically, an equalization circuit is coupled between the output nodes of the low power and low noise differential input circuit.

    Abstract: An analog-to-digital converter (ADC) (112) for sampling high speed video signals includes Pre-amplifiers (502, 504, 506) electrically coupled to Post-amplifiers (508, 510, 512) that are electrically coupled to output latches (514, 517, 519, 521, 523, 525, and 527). A sampling clock signal (116) clocks the output latches (514, 517, 519, 521, 523, 525, and 527) to sample an input analog electronic signal to provide a digital representation thereof. The ADC (112) includes an auto-zeroing function to cancel bias voltages at the Post-amplifiers (508, 510, 512) during a video signal horizontal blanking time period. The ADC (112) includes a bit dithering function by alternating sets of reference voltages into the Pre-amplifiers (502, 504, 506) increasing bit resolution. The ADC (112) includes wired interconnect interpolation between the Pre-amplifiers (502, 504, 506) and Post-amplifiers (508, 510, 512) and between the Post-amplifiers (508, 510, 512) and the output latches (514, 517, 519, 521, 523, 525, and 527).

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.
