Using Real-Time Java for Industrial Control

This compelling video, presented by Randy Rorden, Dir. of Software Development at PTC, shows how Java can be used for real-time IoT edge applications requiring deterministic behavior. The demonstration includes a simulated industrial sorter application with millisecond timing deadlines, written in Java, and running via the PTC Perc real-time Virtual Machine technology. PTC Perc is deployed in many real-world applications requiring sub-millisecond deadline response.

White Paper: A Tale of Java Garbage Collector Delays

A real-time Java Virtual Machine can make a big difference if you have a Java application that needs fast, deterministic response to timed events or external inputs.  While traditional JVMs have reduced pause times, they still suffer from stop-the-world collection phases.  PTC Perc allows high priority threads to preempt the garbage collector to run critical tasks.

White Paper: Real-Time Java for IoT Gateways – When Milliseconds Matter

Gateways are a critical element of the architecture of the Internet of Things.  One of the most useful technologies for implementing IoT gateways is the Java language, runtime, and ecosystem.
