设计者在UCF文件中通过SYSTEM_JITTER关键字指定的系统抖动参数是直接传递至XST静态时序分析工具的。 XST静态时序分析工具使用SYSTEM_JITTER约束时会根据被分析路径中同步元件的数量,按照“和方根”的方式对本路径的系统抖动进行合成,这一点在UG612中并无说明。 一个添加了200ps SYSTEM_JITTER约束的设计,查看布局/布线完成...
20828 - 13.1 Constraints - How can I set the jitter for CLK0 and CLKFX separately (uncertainty)? (INPUT_JITTER/SYSTEM_JITTER) Description When I use CLKFX to drive a system, the clock uncertainty (as used by the Timing Analyzer) is zero if the input clock jitter is set to zero. Conv...
24518 - 14.x/2012.x Timing/Constraints - How can the SYSTEM_JITTER constraint be used? Description How can a value for the SYSTEM_JITTER constraint be generated? Solution The SYSTEM_JITTER constraint is used to represent the power noise, board noise, and any extra jitter of the overall syst...
The system processes the second set of presentation time stamps of the transcoded video stream to determine if the second presentation time stamps include jitter, and based upon determining the second set of presentation time stamps include jitter modifying the second set of presentation time stamps ...
Linux kernel version 5.14 introduces the osnoise tracer that also measures the system jitter / noise. It additionally shows you the sources of the jitter. Example Measure jitter on CPUs 0 through 3: $ taskset -c 0-3 hiccups | column -t -R 1,2,3,4,5,6 cpu threshold_ns hiccups pct...
摘要: A method of estimating the contribution of individual components of multichannel analog-to-digital conversion system to the overall system jitter using correlation properties of noise samplings has been proposed. This method is based on estimating the jitter in noncoherent systems....
ating system jitter Method for emulating operating system jitterMethod for emulating operating system jitter
Techniques for emulating operating system jitter on a platform using a given trace are provided. The techniques include calculating a scale factor, wherein the scale factor is equal to a maximum of measured overhead of introducing synthetic jitter on the platform and a resolution of one or more...

Jitter control and packet loss concealment are accomplished by continuously analyzing buffer content in real-time, and determining whether to provide unmodified playback from the buffer contents, whether to compress buffer content, stretch buffer content, or whether to provide for packet loss concealment...
