Computer interfacing data aquistion and control

Interfacing computers to the external world (the real, time world) is a very important and challenging field. Computers are used to collect me aauremen t data, control industrial processes, display information for theuse of the man, manage the flow of data ••• etc. Theconnection of a computer” to other electrical objects needthe generation of certain signal sequences to guaranteethe reliable and correct timely flow of information.Integrated circuit chips are used for this purposE with both MSI and LSI as prospEctive candidates. It is theaim of my study to evaluate the problems of interfacing electronics in real time computer applications. Thisthesis is a description of a simulator of H-J16 programmed I/O channel, which we developed to be able: to test simpleinterface cards using I/O channels (not direct access devices). It was built and tested sUCCEssfully to thesDecifications included in Chapter
