- Time Improvement Feature and Parallel Measure for 1ms and High (500us) resolution in Seamless Linking Library
- Description
- Time Delay between the sources must be obtained to link from one source to another source
- Once System starts running, SL library will collect the data based on the signal quality
- If Measurement command provided by Application, SL library will do the measurement process according to the Quick Search Modes and resolution (either 1ms or 500us) and obtain the time delay between the sources
- SL library has also an option to provide multiple sources time delay (i.e.: Parallel measurement) based on the resolution if Application requests parallel measure
- SL library will also able to provide precise measure in terms of microseconds or milliseconds based on the microsecond flag set by Application
- Linking to the sources will be done based on the obtained time delay
- Contribution
- Design, Implementation and Unit Testing for Time Improvement feature, Parallel measurement for both 1ms, 500us resolution, Precise measure(us) linking feature
- Gcc and target testing done for the features Time Improvement, Parallel Measure, Precise Measure(uS) linking, TSM, SWA, Highcut, Level alignment using customer shared test streams
