The design of most systems-on-a-chip (SoC) architectures rely on simulation as a means for performance estimation. Such designs usually start with a parameterizable template architecture, and the design space exploration is restricted to identifying the suitable parameters for all the architectural components. However, in the case of heterogeneous SoC(More)
Deep packet processing is migrating to the edges of service provider networks to simplify and speed up core functions. On the other hand, the cores of such networks are migrating to the switching of high-speed traffic aggregates. As a result, more services will have to be performed at the edges, on behalf of both the core and the end users. Associated(More)
A novel paradigm for designing and programming future parallel computing systems called invasive computing is proposed. The main idea and novelty of invasive computing is to introduce resource-aware programming support in the sense that a given program gets the ability to explore and dynamically spread its computations to neighbour processors in a phase(More)
Robust Header Compression (ROHC) provides for more efficient use of radio links for wireless communication in a packet switched network. Due to its potential advantages in the wireless access area and the proliferation of network processors in access infrastructure, there exists a need to understand the resource requirements and architectural implications(More)
The paper presents an overview of a major research project on dependable embedded systems that has started in Fall 2010 and is running for a projected duration of six years. Aim is a 'dependability co-design' that spans various levels of abstraction in the design process of embedded systems starting from gate level through operating system, applications(More)
This paper introduces a scalable hardware and software platform applicable for demonstrating the benefits of the invasive computing paradigm. The hardware architecture consists of a heterogeneous, tile-based manycore structure while the software architecture comprises a multi-agent management layer underpinned by distributed runtime and OS services.

Software accounts for more than 80% of embedded system development efforts, so software performance estimation is a very important issue in system design. Recently, source level simulation (SLS) has become a state-of-the-art approach for software simulation in system level design. However, the simulation accuracy relies on the mapping between source code(More)
