For solving the compatibility problem of the control system to different track vehicle platforms, a track vehicle cross-platform control system is designed, which reduces the development difficulty of track vehicle control system based on different ...

We demonstrate the capabilities of Bolt, an ultra-low-power processor interconnect for the composable construction of new multi-processor wireless embedded platforms. Bolt provides asynchronous bidirectional communication between two processors with ...

The wireless sensor network community is currently undergoing a platform paradigm shift, moving away from classical single-processor motes toward heterogeneous multi-processor architectures. These emerging platforms promise efficient concurrent ...

Safety-critical systems consolidating multiple functionalities of different criticality (so-called mixed-criticality systems) require separation between these functionalities to assure safety and security properties. Performance-hungry and safety-...

The ideas of compiler-generated prefetching were first proposed in the late 80's. Two main research directions were pursued, both addressed prefetching for loop-based applications containing arrays with regular access patterns. Our approach assumed a ...

As embedded systems need more and more computing power, many products require hardware platforms based on multiple processors. In case of real-time constrained systems, the use of scheduling analysis tools is mandatory to validate the design choices, ...

Functional coverage plays a pivotal role in assuring the quality of input stimuli used in the verification of modern digital designs. For an out-of-order multi-processor design, simulation of a detailed model of the design is often required to observe ...

In recent years, portable devices and tablet PCs grow fast and become more convenient and mobile. Applications like multimedia, SIP, and 3D movies become more diverse than before. However, the complex architecture and heavy computing demands increase ...

Garbage collection is a well known technique to increase program safety and developer productivity. Within the past few years, it has also become feasible for uniprocessor hard real-time systems. However, garbage collection for multi-processors does not ...

Virtualization technology has known to be an efficient solution to reduce space and costs by using server consolidation and to provide flexible management of system resources. The widely used virtual machine monitor (VMM) such as Xen is not perfectly ...

The XMOS XK-XMP-64 is an experimental multi-processor board that demonstrates the scalability of the XS1 architecture; it connects 64 XCore processors, providing 512 hardware threads and 25.6 GIPS aggregate performance. This paper briefly overviews the ...

The use of automata for specifying patterns of task generation has broaden the perspective of schedulability analysis; scheduling has moved from periodic or rate-monotonic to aperiodic and non-uniform tasks. The question of schedulability in this ...

The technique of deterministic record and replay aims at faithfully reenacting an earlier program execution. For concurrent programs, it is one of the most important techniques for program understanding and debugging. This demo presents LEAP: an ...

The technique of deterministic record and replay aims at faithfully reenacting an earlier program execution. For concurrent programs, it is one of the most important techniques for program understanding and debugging. The state of the art deterministic ...

The design of new embedded systems is getting more and more complex as more functionality is integrated into these systems. To deal with the design complexity, a predictable design flow is needed. The result should be a system that guarantees that an ...

In recent years, Model calibration and parameter estimation with high complexity is a common problem in many areas of researches, especially in environmental modeling. This paper proposes a comparatively simple technique on the parallel implement of ...

Modern embedded multi-processors can execute several stream-processing applications concurrently. Typically, these applications are partitioned into tasks that communicate over buffers together forming a task graph. The fact that these applications are ...

CPU scheduler is a very important subsystem which affects system throughput, interactivity and fairness. The development of Linux kernel is relatively fast-paced. By now, many CPU schedulers have been designed by researchers, hobbyists and kernel ...

Garbage collection (GC) is a well known approach to simplify software development. Recently, it has started to gain acceptance also in the real-time community. Several hard real-time GC algorithms have been proposed for uniprocessors. However, the ...

This brief announcement presents a pair of performance laws that bound the change in aggregate job queueing time that results when the processor speed changes in a parallel computing system. Our laws require only lightweight passive external ...
