Abstract :
In a balloon-borne experiment, signals from detectors are processed in a balloon-borne apparatus so as to comply with data bandwidth of a storage device installed in the apparatus. The process begins at front-end processors receiving signals from detectors and proceeds under successive stages by dedicated processors. Event data are finally fed to a computer bank for post trigger selection where the events are further selected before being written into the storage device. The computer bank is made of transputer modules. The transputers are widely employed and some processors are implemented by the transputers. How the processors are integrated is described together with function and implementation of the individual processors.<>
