Data Acquisition

Recently, (6/99) I've been revisiting the issues surrounding data acquisition and control of hardware on PCs under various operating systems. Herewith a collection of notes.

Topics List

• Multitasking discussion: Basics of Processes, Threads, Time Slices and Priority
   
• Precision Timing Under Windows OSes: Measuring Time, and Scheduling Routines under Windows. Checking the Scheduler granularity. Numerous references.
   
• Observing Timing Behavior of Applications in Windows 95/98/NT Using LabVIEW: How well can applications that you write in LabVIEW or other languages perform under Windows OSes?  Does LV use Special Magic or simply make most judicious used of the OS timing services?
   
• Port I/O Under NT:  Part of my collection of Delphi pages:  Notes on how to use Delphi (or other languages) to perform Port I/O under NT.
