Copenhagen Programming Language Seminar


Resilient: Making Embedded Systems Serviceable

Lars Bak

WEDNESDAY, May 19th, 15:15-16:00
ITU, Glentevej 67, room 2.03


Developing software for embedded systems has until now been very static. Source code, written in C, is compiled and linked on the development platform and the resulting binary image is transferred onto the device. In an industry where robustness is paramount and dynamic software updates are required, this is simply not good enough. This presentation will describe a new approach to developing software for embedded devices. At the bottom of the software stack we have replaced the operating system with a Smalltalk based virtual machine. Scheduler,interrupt handlers, device drivers, networking code and application software are executing on top of this virtual machine. We will discuss some of the design decisions behind this dynamic, lean and mean system for embedded devices. The approach solves many software related problem within the embedded industry. The two biggest problems are full serviceability and transparent software updates. We will conclude with a demonstration of the Resilient programming environment and embedded platform.

Bio: Lars is a technology industry veteran with more than 15 years experience in virtual machine technology, product engineering and management. Prior to founding OOVM in 2002, Lars was one of the architects of the Java HotSpot virtual machine at Sun Microsystems,Inc., a highly successful product with many million installations worldwide. At Sun, Lars was also the main architect of the CLDC HotSpot virtual machine, a new high-performance system for mobile phones. Lars holds a MS degree in Computer Science and is inventor on numerous patents within virtual machine technology.
