Simulation of input-output units

Abstract

The concept of simulation - hardware or software - has been expanded to the creation of logical entities that correspond to real identities, to existing machines, or even to configurations that have no physical counterpart. Here we deal with the Input/Output aspect only. In order to simulate an input/output unit, we propose to define a comprehensive language, easy to use, and capable of describing operations of the device on line with any computer. Only devices using 360 or 370 architecture may be described, but there are no difficulties to describe any kind of device with a slight extension of the language.
