Introduction
Effective Frame Per Second & Pipeline Operation
Formulas
Use the following formula to calculate effective FrameRatePerSecond in a
Visionscape
EFPS =
Where VS Overhead is typically:
Interrupt Latency + Framework Overhead = 0.5 msec max
Or
EFPS =
In Table 1–2, EFPS is given in PowerStrobe with 1msec Integration time and Job
in full pipeline, meaning that the Job tools + idle processing time, i.e., less than
(IT + VFT + 0.5) above.
Full Pipeline = (AVT AVP Processing Time + IDT Inspection Idle Time +
LossLess Connection Overhead) < (IT + VFT + VSO) idle time is defaulted to
3% of the Inspection Time as defined in the VisionSystemStep property page.
Table 1–2 lists Visionscape
frames per second.
