A detector is being constructed at Fermilab to investigate antiproton - proton collisions at up to 2 TeV center of mass energies. The detector will have approximately 75,000 channels of electronics with an expected occupancy of about 10% for typical events. The ultimate raw event rate is expected to be 50 KHz, with events being written to magnetic tape at a rate of 5 Hz. We are designing a FASTBUS based data acquisition system incorporating multiple processors running concurrently to do the necessary data compaction and filtering. Numerous local intelligences allow the system to be broken into independent subsystems for checkout and calibration.
