Search of a state transition system is traditionally how deadlock detection for concurrent programs has been accomplished. This paper examines an approach to deadlock detection that uses geometric semantics involving the topological notion of dihomotopy to partition the state-space into components; after that the reduced state-space is exhaustively searched. Prior work partitioned the state-space...
Deadlock detection for concurrent programs has traditionally been accomplished by symbolic methods or by search of a state transition system. We examine an approach that uses geometric semantics involving the topological notion of dihomotopy to partition the state-space into components, after which the reduced state-space is exhaustively searched. Prior work partitioned the state-space inductively,...
This paper concerns the design and verification of a realtime communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to define and verify the correctness in the presence of these lost data frames under real-time constraints. This paper describes a temporal...
