Program assertions typically operate on available program state such as global and local variables. To support sophisticated assert statements such as invariants on control flow or inter-process communication patterns, developers must design and maintain supporting infrastructure. It is non-obvious how to realize this infrastructure: how to maintain the data, how to access it, how to use it in assertions,...
Developers of performance sensitive production software are in a dilemma: performance regression tests are too costly to run at each commit, but skipping the tests delays and complicates performance regression detection. Ideally, developers would have a system that predicts whether a given commit is likely to impact performance and suggests which tests to run to detect a potential performance regression...
With the growth of complexity in the embedded domain, the use of distributed systems to support multiple realtime applications has become commonplace. These applications may share processor and network resources, and real-time scheduling policies can guarantee that these applications do not interfere with each other's ability to meet their temporal constraints. We believe that these applications should...
The complexity of real-time systems has substantially increased in the past few years regarding both hardware and software aspects. The use of modern sensors, able to capture image and audio data, demands predictable multimedia-like data processing. Moreover, applications like autonomous robots, surveillance, or modern multimedia players may well be characterized by several operation modes, each one...
Due to modularity and heterogeneity in Wireless Sensor Networks sensing devices, a sensor application developed for a given platform will seldom be portable to a different one, unless the run-time support systems on those platforms deliver mechanisms that abstract and encapsulate the sensor platform in an adequate manner. In this article we propose a software/hardware interface that is able to abstract...
