Abstract:

The Air Force Materials Laboratory AFML uses LSI-11 microcomputers as one of several computer systems available for collecting test data. For conducting these tests, LSI-11 programs must be loaded into and data collected from the LSI-11 using paper tapes. Data is later stored on a larger computer system at AFML, the SEL 86. The purpose of this investigation has been to design a SEL 86LSI-11 interface that will automate manual procedures. The interface design enhances the current LSI-11 system by providing the following capabilities load binary programs and data residing on a SEL 86 file into LSI-11 memory transmit data stored in LSI-11 memory to one or more SEL 86 files, and place the LSI-11 memory into a transparency mode such that it is a peripheral as viewed by the SEL 86. The principles of software engineering have been applied in both the analysis and design phases. Formal tools have been used in defining the requirements and developing the structured design. The resulting design is an interface monitor with software residing on both the LSI-11 and the SEL 86. The added capabilities are provided using either a series of commands entered at the LSI-11 console or as call statements in LSI-11 FORTRAN compiled programs. Author
