Abstract

ABSTRACTThe AN/UYK‐502 Microcomputer is a full‐scale, general‐purpose 16‐bit militarized computer designed to emmulate the AN/UYK‐20 and AN/AYK‐14, and to be implemented in a shipboard system employing distributed system architecture. Ship System Data Busses require microcomputers to be located near or within ship subsystems, with system interconnection being made through a common data bus. To implement this type of system architecture, a low cost, modular microcomputer capable of handling the bus “handshake” through a standard interface is required.The AN/UYK‐502(V) uses software common to minicomputers which allows different computer configurations to be implemented with bus architecture. The resulting system can then be maintained with a single set of support software programs thus significantly lowering system life cycle costs. The computer is offered in three physical packages: the Card Kit, Chassis Assembly, and Cabinet Assembly.Flexible options of the AN/UYK‐502(V) allow the user to tailor the system to the application needs. These options include the Central Processing Expansion Unit; main memory up to 2S6K (where K = 1024); memory parity; choice of 1 to 64 input/output (I/O) channels; parallel and/or serial I/O; and power supply selection.
