The document discusses a novel processor designed for real-time garbage collection in embedded systems, which enhances programmer productivity and software quality with minimal overhead. This processor operates autonomously, eliminating the interruptions typically associated with traditional software-based garbage collection. It is currently represented by a prototype developed by researchers at the University of Stuttgart, aimed at facilitating commercialization.
Processor with integrated real time garbage collection
- 1. Electrical Engineering | Technology Offer Processor with Integrated Real-Time Garbage Collection Application Area Object-oriented programming languages with garbage collection such as Java considerably increase programmer productivity and software quality. A novel processor with hardware extensions for garbage collection permits the use of these robust programming languages even in systems with hard real-time requirements. Your Benefits at a Glance Suitable for systems with hard real-time require- ments (in particular embedded systems) Technological Challenge Low garbage collection overhead While garbage collection offers substantial benefits No interruptions caused by garbage collection for the design of highly reliable systems, it is Extremely robust due to object-based memory extremely difficult to implement garbage collection protection both efficiently and suitably for real-time systems. Fully operational prototype (including a Java compiler) Today, garbage collection is exclusively realized in software and causes pauses of unpredictable Patent Portfolio duration or suffers from considerable runtime overhead.
