Squawk JVM and Runtime
- Motivations : Memory constrained devices
- Fully capable J2ME-level Java VM with OS functionality
- Features
- No operating system : Runs on the bare metal on ARM
- Device driver are written in Java
- Isolate application model (sub/super set of JSR121)
- Inter-isolate communication
- Provides lower-level asynchronous message delivery
- Memory footprint : 80K for the VM, 270K for the Runtime
