Current multi-core design methodologies are facing increasing unpredictability in terms of quality due to the actual diversity of the workloads that characterize the deployment scenario. To this end, these systems expose a set of <i>dynamic parameters</i> which can be tuned at run-time to achieve a specified <i>Quality of Service</i> (QoS) in terms of(More)
Technology trends enable the integration of many processor cores in a System-on-Chip (SoC). In these complex architectures, several architectural parameters can be tuned to find the best trade-off in terms of multiple metrics such as energy and delay. The main goal of the MULTICUBE project consists of the definition of an automatic Design Space Exploration(More)
Nowadays, owing to unpredictable changes of the environment and workload variation, optimally running multiple applications in terms of quality, performance and power consumption on embedded multi-core platforms is a huge challenge. A lightweight run-time manager, linked with an automated design-time exploration and incorporated in the host processor of the(More)
Since the application complexity is growing and applications can be dynamically activated, the major challenge for heterogeneous multiprocessor platforms is to select at runtime an energy-efficient mapping of these applications. Taking into account that many different possible implementations per application can be available, and that the selection must(More)
In an MP-SoC environment, a customized run-time management should be incorporated on top of the basic OS services to globally optimize costs (e.g. energy consumption) across all active applications, according to constraints (e.g. performance, user requirements) and available platform resources. To that end, we have proposed a Pareto-based approach combining(More)
The main goals of the 2PARMA project are: the definition of a parallel programming model combining component-based and single-instruction multiple-thread approaches, instruction set virtualisation based on portable byte-code, run-time resource management policies and mechanisms as well as design space exploration methodologies for many-core computing(More)

MATISSE is a design environment intended for developing systems characterized by a tight interaction between control and data-flow behavior, intensive data storage and transfer, and stringent real-time requirements. Matisse bridges the gap from a system specification, using a concurrent object-oriented language, to an optimized embedded single-chip(More)
