摘要： An analog-to-digital-converter (ADC) timing engine may simplify the use of Delta-Sigma ADCs by compensating for the group-delay of the ADC. The compensation may render the group-delay corresponding to the ADC largely transparent to the end-user of the ADC. Therefore, multiple ADCs may be easily synchronized with each other, even if they have different group-delays, and they may further be synchronized with other types of ADCs that do not have group-delays. The data from the ADCs may also be synchronized with external events. The ADC timing engine (ATE) may be programmed with a number of parameters to set proper delays taking into account not only the group-delays corresponding to the various ADC, but delays stemming from a variety of other sources. Multiple ATEs may be synchronized with each other to ensure that data acquisition by the participating ADCs is started and/or stopped at the same point in time.
摘要翻译：模数转换器（ADC）定时引擎可以通过补偿ADC的组延迟来简化Delta-Sigma ADC的使用。该补偿可能会使与ADC最终用户相对应的ADC延迟很大程度上是透明的。因此，即使它们具有不同的组延迟，多个ADC也可以彼此容易地同步，并且它们可以进一步与没有组延迟的其他类型的ADC同步。 ADC的数据也可能与外部事件同步。 ADC定时引擎（ATE）可以用多个参数进行编程，以便设置适当的延迟，不仅考虑到与各种ADC相对应的组延迟，而且还考虑到来自各种其他源的延迟。多个ATE可以彼此同步，以确保参与的ADC的数据采集在同一时间点开始和/或停止。

摘要： Various embodiments of a system and method for performing a measurement application are described herein. The system may include a host computer having a processor, and a measurement device having a programmable hardware element. The programmable hardware element may be configured to perform a loop to acquire measurement data from a physical system. The host computer may be configured to perform another loop to read the measurement data from the programmable hardware element and use the measurement data in a measurement and control algorithm. The host computer may be further configured to perform a synchronization algorithm to keep the measurement data acquisition loop performed by the programmable hardware element synchronized with the measurement and control loop performed by the host computer.
