\begin{abstract}
|
|
|
49 |
Despite the wide use of Priority Inheritance Protocol in real time operating
|
|
|
50 |
system, it's correctness has never been formally proved and mechanically checked.
|
|
|
51 |
All existing verification are based on model checking technology. Full automatic
|
|
|
52 |
verification gives little help to understand why the protocol is correct.
|
|
|
53 |
And results such obtained only apply to models of limited size.
|
|
|
54 |
This paper presents a formal verification based on theorem proving.
|
|
|
55 |
Machine checked formal proof does help to get deeper understanding. We found
|
|
|
56 |
the fact which is not mentioned in the literature, that the choice of next
|
|
|
57 |
thread to take over when an critical resource is release does not affect the correctness
|
|
|
58 |
of the protocol. The paper also shows how formal proof can help to construct
|
|
|
59 |
correct and efficient implementation.
