is also a term used in real-time computing
. In a fashion somewhat comparable to the moving-picture definition presented above, a real-time frame
is the time it takes to complete a full round of the system's processing tasks. If the frame rate of a real-time system is 60 hertz
, the system reevaluates all necessary inputs and updates the necessary outputs 60 times per second under all circumstances.
Owing to their flexibility, software-based video formats can specify
arbitrarily high frame rates, and many (cathode ray tube) consumer PC
monitors operate at hundreds of frames per second, depending on the
selected video mode. LCD screens are usually 24, 25, 50, 60, or 120 FPS.
The designed frame rates of real-time systems vary depending on the equipment. For a real-time system that is steering an oil tanker
, a frame rate of 1 FPS may be sufficient, while a rate of even 100 FPS may not be adequate for steering a guided missile
. The designer must choose a frame rate appropriate to the application's requirements.http://www.mercedesbenzwheel.com
