Paper Abstract

An Interactive Multitasking Executive has been developed based on Digilab's FTS software and Data General's RDOS(R) general purpose disc operating system. The use of RDOS as a basis for IMX results in a file oriented system, providing file maintenance, protection and disc memory management, multitasking environment, expandability in memory mapped systems and capability for using higher level languages and foreground/ background operation. Furthermore, IMX utilizes the RDOS spooling feature. This allows device commands to be buffered as they are generated by IMX and to be transferred to the peripheral devices at their slower rate, thus enhancing system throughput. The IMX system permits the operation and control of the Fourier Transform Spectrometer through a simple and user-oriented command and parameter structure, which can be expanded with user created command and stored parameter tables. Multi-spectrometer and multitask operation is trivially achieved by the user due to the operating system memory resource allocation. Examples of multitasking multispectrometer and various user program applications are provided. The application of IMX to Gas Chromatography/Infrared (GC/IR) measurements and the generation "infragrams" (reconstructed functional group chromatograms) is discussed.
