Application Scenarios in Streaming-Oriented Embedded System
In the past decade real-time embedded systems
became more and more complex and pervasive. From the user
perspective, these systems have stringent requirements regarding
size, performance and energy consumption, and due to business
competition, their time-to-market is a crucial factor. Therefore,
much work has been done in developing design methodologies
for embedded systems to cope with these tight requirements. In
this paper, we introduce the concept of application scenarios that
group operation modes of an application that are similar from the
resource usage perspective, and we describe how to incorporate
them in the overall real-time embedded system design process. A
case study shows the use of application scenarios for low energy
design, under both soft and hard real-time constraints.
