There are all kinds of virtual machines (VM) available and many are being employed in embedded applications. Platforms like the Java virtual machine (JVM) are used on servers and embedded applications with features like garbage collection. Unfortunately, these can have a lot of overhead making them less desirable for small, microcontroller-based systems. Rolf Segger, Founder of Segger Microcontroller Systems, talks about the company's new emApps virtual platform.
