Kitt Peak Multi-Tasking FORTH-It
نویسنده
چکیده
An overview of the Kitt Peak National Observatory (KPNO) real-time environment is presented. The eleven optical telescopes at Kitt Peak employ a variety of experimental instruments, including Fourier Transform Spectrometers and large array digital cameras, that impose a diverse set of real-time requirements. Presented next will be a historical perspective of FORTH and KPNO over the last decade outlining the evolution of the embryonic version of FORTH on an 8K mainframe (CDC), mini (Digital VAX-II and PDP-II), and micro (Digital LSI-II) machines. The real-time attributes of FORTH in general and KPNO multi-tasking FORTH-II in particular are discussed. Some details of the implementation of FORTH-II are presented to reveal the power of this real-time programming environment. Finally, the KPNO CCD camera system will be used to illustrate a complex real-time application of multi-tasking FORTH-II.

Practical and theoretical aspects of FORTH software development
This is an investigation into the use of the Forth programming environment. The main areas of enquiry were: interfacing Forth to other languages; interfacing Forth and local area networks; and the use of RISC processors with stack based architecture such as the NC4000 and Harris RTX series. We describe how t o i n terface Forth a n d C. W e also provide a system with a multi-tasking interrupt d...
متن کاملAdapting the Multi-Desktop Paradigm Towards a Multi-Context Interface
Knowledge workers are typically processing multiple tasks in parallel. As humans can concentrate and work on but one task at a time, users have to switch between them. The required task switching causes a high cognitive load and decreases efficiency. To reduce the costs of these task switches, we have to find ways to cope with a multitude of dormant tasks the user might switch to again. The cha...
متن کاملBuilding an LR parser for Pascal using Forth
The construction of a parser for Pascal is described. The parser is built by using Forth to include files that define the tokens and grammar of the language and may be thought of as a ‘virtual machine’ comprising a grammar code with lookup tables. The resulting parser can be run from within Forth or any other environment using simple drivers and is fully LR(1) capable. It is also well-suited fo...
متن کاملWho Multi-Tasks and Why? Multi-Tasking Ability, Perceived Multi-Tasking Ability, Impulsivity, and Sensation Seeking
The present study examined the relationship between personality and individual differences in multi-tasking ability. Participants enrolled at the University of Utah completed measures of multi-tasking activity, perceived multi-tasking ability, impulsivity, and sensation seeking. In addition, they performed the Operation Span in order to assess their executive control and actual multi-tasking ab...
متن کاملGuide to the Kitt Peak Coude Slit Reduction Task DOSLIT
The IRAF kpcoude.slit package is specialized for the extraction, sky subtraction, wavelength calibration, and flux calibration of Kitt Peak coude slit spectra. It contains the general tools needed for each of the reduction steps. However, the main emphasis of this package is the task doslit to streamline the complete data reduction. This guide describes what this task does, it’s usage, and para...
