Partitioning: The duality of software
and hardware
•
•
The hardware and software in an embedded system work together to solve
a problem ( algorithm )
The decision about how to partition the software components and the
hardware components is usually dictated by speed and cost
- Dedicated hardware is fast, inflexible and expensive
- Reconfigurable hardware is fast, flexible and more expensive
- Software is slower, more flexible and cheaper
