hard real-time

基本解釋

With a little extra work, you can get hard real-time support with the PREEMPT_RT patch.
衹需要一點額外的工作，您就可以通過 PREEMPT_RT 補丁實現(xiàn)硬實時。
Some systems need hard real-time response, with short deterministic response latencies to events.
一些系統(tǒng)需要硬實時響應(yīng)，在很短的時間內(nèi)對事件作出確定性響應(yīng)。
For financial applications where time is money the critical sections can be coded to run as hard real-time threads and avoid the non-deterministic behaviour of the garbage collector.
對金融系統(tǒng)這種“時間就是金錢”的應(yīng)用程序來說，可以讓臨界區(qū)的代碼做爲硬實時線程運行，從而避免垃圾廻收器産生的不確定性行爲。

This makes it hard, for instance, to compare real-time video images (from a camera in the nose-cone of a missile, for example) with a set of several thousand targets (pictures of enemy aircraft, say), because all the targets have to be tested within a thirtieth of a second, the duration of a single frame of video.
ECONOMIST: Optical recognition
