Improving early design stage timing modeling in multicore based real-time systems

This paper presents a modelling approach for the timing behavior of real-time embedded systems (RTES) in early design phases. The model focuses on multicore processors - accepted as the next computing platform for RTES - and in particular it predicts the contention tasks suffer in the access to multicore on-chip shared resources. The model presents the key properties of not requiring the application's source code or binary and having high-accuracy and low overhead. The former is of paramount importance in those common scenarios in which several software suppliers work in parallel implementing different applications for a system integrator, subject to different intellectual property (IP) constraints. Our model helps reducing the risk of exceeding the assigned budgets for each application in late design stages and its associated costs.This work has received funding from the European Space Agency under Project Reference AO=17722=13=NL=LvH, and has also been supported by the Spanish Ministry of Science and Innovation grant TIN2015-65316-P.

Software process improvement in graduate software engineering programs

At the École de technologie supérieure (ÉTS), software process improvement (SPI) is taught in lecture format and with a 10-week implementation project in an organization by teams of students of the graduate software engineering curriculum. The SPI course is taught using a ‘problem- goal-solution’ approach where students learn that any process improvement initiative must be based on issues preventing an organization in achieving its organizational goals whether the organization is a company or a not-for- profit organization. An important aspect of this course is the management of technological change where students learn and put in practice in their project the ‘soft’ issues which are part of most SPI organizational initiatives
