Understanding INtime
software architecture
This chapter explains how the RT kernel works with Windows to provide real-time
functionality. It also lists and describes INtime components.
How INtime software and Windows work together to run RT applications
When an INtime application runs on an INtime node, Windows threads communicate
with RT threads via the Windows extension (NTX) library as shown in this figure:
