A Case Study in Codesign of Distributed Systems
-- Vehicle Parking Management System
Hardware-software codesign of distributed systems is a more challenging
task than that of centralized embedded systems. Each phase of codesign,
such as copartitioning, cosynthesis, cosimulation, and coverification,
must take into account physical restrictions imposed by the distributed
nature of such systems. Although codesign of distributed systems is more
complex, yet many common parts of the systems can be reused for codesign.
For the above two reasons, we have adopted an object-oriented (OO) codesign
approach, which allows a natural structural restriction and object design
reuse. A parallel approach to hardware-software partitioning is also
presented. We illustrate our techniques through a case study on a Vehicle
Parking Management System (VPMS). The study shows the benefits of OO
codesign and parallel partitioning. Validation is accomplished through
prototyping and emulation.
