Ubiquitous Systems
Systems interacting in an environment
tend to have limited resources
• Hardware
• Software

Problems encountered
in BodyHopper project
• Port Forth compiler to PalmOS
- jumps over 32K-code segments
• Infrared communication
- low level interrupt handling
• Hop procedure
- load both program and stack
Further timing problems with debug-statements
