Multiprocessor data acquisition for NordBall
- 1. Niels Bohr Inst., Copenhagen (Denmark)
Description
For the NordBall multidetector system a versatile data acquisition system has been developed around the VME bus utilizing 68010 processors. The readout of the instrument is based on a generalized READER concept. READERs are CPU boards reading hardware in parallel for each event. In the FERA bus the final fast logical decision is made before an event is to be considered as being present for readout. Synchronization with the trigger for readout, coming from the FERA bus system, is performed by a special hardware unit. Synchronization on event level between the READERs is done by the same hardware unit monitored by a master CPU. (orig.)
