✦ Synopsis

In recent years there have been many attempts in high energy physics to make trigger and decision processes faster and more sophisticated. This became necessary due to a permanent increase of the number of sensitive detector elements in wire chambers and calorimeters, and in fact it was possible because of the fast developments in integrated circuits technique.

In this paper the present situation will be reviewed. The discussion will be mainly focussed upon event filtering by pure software methods andrather hardware relatedmicroprogrammable processors as well as random access memory triggers.
