A QNX-based medical demo equipped with PPS messaging and a Qt user interface. |
In a nutshell, PPS lets you create loosely coupled designs based on asynchronous publications and notifications. This “decoupling” offers a great deal of flexibility, allowing you to delay final decisions on module connection points and data flow until runtime. Because such decisions don’t have to be hardcoded, they can be adapted as requirements evolve; they can even change dynamically as the system runs.
It's almost 18 months later, and the two posts remain in the top 10 of my most popular articles. Just one problem: Neither post discusses how PPS could be applied to medical devices — Quelle horreur!
Fortunately, my QNX colleague Justin Moon has filled the gap with the article "Persistent Publish/ Subscribe Alleviates Development Pains in Medical Devices." Read it here in Medical Electronic Device Solutions (MEDS) magazine.
