A deep ocean capsule is proposed capable of sensing pressure, temperature, flow and direction for a study of tides and internal waves of the oceans. One of the major requirements for this capsule is the detection and recording of unusual events. To meet this need a very low power, highly reliable digital detector has been designed. COSMOS logic with maximum use of MSI and LSI was used in the design. The detector was simulated using proposed word lengths and fixed point arithmetic which would be utilized in the ensuing hardware. The fixed point simulation was necessary to verify the problems in truncation and round-off errors and to provide necessary design criteria to ensure proper filter functioning and integral detection.
