Abstract

A parallel scalable Data Acquisition System, based on VME, has been developed to be used in the FINUDA experiment, scheduled to run at the DAFNE machine at Frascati starting from 1997. The acquisition software runs on embedded RTPC 8067 processors using the LynxOS operating system. The readout of event fragments is coordinated by suitable trigger Supervisor. Data read by different controllers are transported via dedicated bus to a Global Event Builder running on a UNIX machine. Commands from and to VME processors are sent via socket based network protocols. The network hardware is presently ethernet, but it can easily changed to optical fiber.
