Abstract
-
In the study phase of the project to provide a general purpose laboratory facility for use in research in training simulation techniques, digital computer systems and interface equipments were evaluated for the application. Criteria for the system evaluation were obtained from previous studies, involving the F100A aircraft and EROS vehicle flight simulations using the UDOFT computer facility. Requirements for the computer hinge on a real on a real time operating capability which stresses high computation rates. Significant characteristics include: (1) An operating rate in excess of 75,000 instructions per second on flight simulation problems. (2) A memory capacity of at least 8,000 words, (3) A computer word length of at least 24 bits, and (4) At least three index registers. The result of the study phase is a recommendation of the Packard Bell 440 as the central computer of the simulation system; and as an alternative, a recommendation of the faster SDS 9300 computer is made provided its higher cost and later delivery time are acceptable. The recommended interface equipment will include a multiplexed analog-to-digital conversion subsystem capable of digitizing 32 input channels to 12 bits at a rate in excess of 35,000 conversions per second, a dual resolution digitalto-analog conversion system supplying 64 analog outputs to analog equipment, 72 sense inputs, 72 control outputs, and a digital interval timer.
