This paper presents a programming model approach that explicitly addresses the programmability of scientific code by annotating imperative code with its algorithmic structural behavior. This information is used to create hierarchical structures, as opposed to the flat structure that most programming models work with, which allows sound code transformation at any level of the code, adjusting the granularity...
Multicore embedded systems are rapidly emerging. Hardware designers are packing more and more features into their design. Introducing heterogeneity in these systems, i.e. Adding cores of varying types does provide opportunities to solve problems in different aspects. However, this presents several challenges to embedded system programmers since software is still not mature enough to efficiently exploit...
This work describes how we use High-Level Synthesis to support design space exploration (DSE) of heterogeneous many-core systems. Modern embedded systems increasingly couple hardware accelerators and processing cores on the same chip, to trade specialization of the platform to an application domain for increased performance and energy efficiency. However, the process of designing such a platform is...
Wireless Sensor Networks (WSNs) are rapidly becoming a necessary tool in many different application areas, such as environmental monitoring, security, safety, and so on. The heterogeneity of hardware is large, so there exists several different environments that support WSN programming. However, the great majority of such environments only target the sensors programming, forgetting about their real...
Currently multicore systems start to be used even in low-end devices such as embedded systems controllers requiring real-time guarantees. Hardware Transactional Memory (TM) is a new synchronization paradigm for this architecture, allowing problems of lock-based methods and making easer programming. We propose to use TM to synchronize the concurrent/parallel execution of the Garbage Collector (GC)...
This paper proposes an architecture concept to the design of software, for embedded systems and cooperating embedded systems, aimed to simplify not only design but also reuse and reconfigurability. The concept is targeted at software for recurring signal processing and control tasks common in industrial embedded supervision and control applications. An important part of the architecture concept is...
The wide increase of total processing cores in commodity processors tends to lighten the need for computer performance by the classical scientific problems as well as by the modern multimedia and every day embedded applications. Nevertheless, the introduction of this powerful and promising technology seems to inherit and in some cases magnify all the classical problems that already exist on the programming...
We have previously proposed PTIDES (programming temporally integrated distributed embedded systems), a discrete-event framework that binds realtime with model time at sensors, actuators, and network interfaces. In this experimental effort we focus on performance issues and tradeoffs in PTIDES implementation. We address event processing performance with respect to other distributed discrete event approaches...
