| Problem |
In an era of reduced budgets, many projects are
considering versions of
the Linux operating system to lower cost. Some of these versions are
modified to operate in a real-time and embedded environment. However,
the safety, reliability, and applicability of these operating systems
has not been thoroughly categorized. |
| Objective |
The objective of this research is to
characterize 3 to 5 real-time
Linux operating systems from a safety, reliability, and applicability
perspective. This includes determining the strengths and weaknesses of
the various operating systems, cataloging their error and fault and
performing functional analysis and testing to compare the with the
VxWorks operating system. |
