Virtual machine programming system

摘要

A system for programming a computer provides a set of software-based virtual machines each for instructing a computer to carry out a selected operation. Each virtual machine is represented by a virtual front panel displayed on a screen and each virtual front panel graphically displays operator controllable values of input and output parameters utilized by the virtual machine it represents. The system is adapted to synthesize a new virtual machine for instructing the computer to perform a sequence of operations wherein each operation is carried out by the computer according to the instructions of an operator selected one of the existing virtual machines. The system also creates a new virtual front panel for displaying input and output parameters associated with the new virtual machine. The system permits the operator to program the computer by directing synthesis of a hierarchy of virtual machines.
