Abstract :
Summary form only. With the advent of silicon multistrip revelators, the problem of monitoring all their channels (in the present case ~40000) in a relatively short time, before or during data acquisition, becomes important. To do that, a system has been developed that takes data from the `serial´ front-end of the relevator and processes them in an online style, giving the results to the Experiment Computer Cluster. This is done with 12 boards accommodating two 2048 words×27 bits FIFOs each, that will hold an event, and with a computing engine (a 30-MHz 38030 with 12 MBytes of RAM) with one Ethernet port to connect it to the other computers
