A large number of embedded systems include 8-bit microcontrollers for their energy efficiency and low cost. Multi-bank memory architecture is commonly applied in 8-bit microcontrollers to increase the size of memory without extending address buses. To ...

In this paper, we present a novel system modeling language which targets primarily the development of source-level multiprocessor memory aware optimizations.

In contrast to previous system modeling approaches this approach tries to model the whole ...

Coarse Grain Reconfigurable Architectures (CGRAs) promise high performance at high power efficiency. They fulfil this promise by keeping the hardware extremely simple, and moving the complexity to application mapping. One major challenge comes in the ...

Many embedded applications demand processing of a seemingly endless stream of input data in real-time. Productive development of such applications is typically carried out by synthesizing software from high-level specifications, such as data-flow ...

This paper extends the methodology of analytic real-time analysis of distributed embedded systems towards merging and extracting sub-streams based on event type information. For example, one may first merge a set of given event streams, then process ...

Concurrent Action-Oriented Specifications (CAOS) model the be- havior of a synchronous hardware circuit as asynchronous guarded actions at an abstraction level higher than the Register Transfer Level (RTL). Previous approaches always considered the ...

We describe the extension of a reactive programming language with a behavioral contract construct. It is dedicated to the programming of reactive control of applications in embedded systems, and involves principles of the supervisory control of discrete ...

Embedded systems are widely used for supporting our every day life. In the area of safety-critical systems human life often depends on the system's correct behavior. Many of such systems are hard real-time systems, so that the notion of correctness not ...

With increasingly more complex Multi-Processor Systems on Chip (MPSoC) and shortening time-to-market projections, Transaction Level Modeling and Platform Aware Design are seen as promising >approaches to efficient MPSoC design.

In this paper, we present ...

Chip multiprocessors (CMPs) are expected to be the building blocks for future computer systems. While architecting these emerging CMPs is a challenging problem on its own, programming them is even more challenging. As the number of cores accommodated in ...

The issues of compiler optimization phase ordering and selection present important challenges to compiler developers in several domains, and in particular to the speed, code size, power, and cost-constrained domain of embedded systems. Different ...

DSP processors usually provide dedicated address generation units (AGUs) to assist address computation. By carefully allocating variables in the memory, DSP compilers take advantage of AGUs and generate efficient code with compact size and improved ...

Over the past decade, system architectures have started on a clear trend towards increased parallelism and heterogeneity, often resulting in speedups of 10x to 100x. Despite numerous compiler and high-level synthesis studies, usage of such systems has ...

The automotive industry has a growing demand for the seamless integration of safety analysis tools into the model-based development toolchain for embedded systems. This requires translating concepts of the automotive domain to the safety domain. We ...

For its high overall cost during product development, program debugging is an important aspect of system development. Debugging is a hard and complex activity, especially in time-sensitive systems which have limited resources and demanding timing ...

Continuous technology scaling has brought us to a point, where transistors have become extremely susceptible to cosmic radiation strikes, or soft errors. Inside the processor, caches are most vulnerable to soft errors, and techniques at various levels ...

In preemptive real-time systems, scheduling analyses need - in addition to the worst-case execution time - the context-switch cost. In case of preemption, the preempted and the preempting task may interfere on the cache memory.

This interference leads ...

In this paper, we propose a hybrid-level flash translation layer (FTL) called RNFTL (Reuse-Aware NFTL) to improve the endurance and space utilization of NAND flash memory. Our basic idea is to prevent a primary block with many free pages from being ...
