In this work, we first present an application-initiatedstrategy that aims to control the energy consumption,while simultaneously enhancing the performance of aheterogeneous embedded system. We assess the benefitsof using this strategy by means of a traditional ...

We present a methodology for microarchitectural customization of embedded processors by exploiting application information, thus attaining the twin benefits of processor standardization and application-specific customization. Such powerful techniques ...

Abstract¿Real-time distributed applications have timing constraints on tasks running on several processors. To design real-time systems with end-to-end performance requirements, we need to have algorithms to schedule and to coordinate tasks on different ...

Feasibility and schedulability problems have received considerable attention from the real-time systems research community in recent decades. Since the publication of the Liu and Layland bound, many researchers have tried to improve the schedulability ...

A flexible test architecture for embedded cores and all interconnects in a System-on Chip (SOC) is presented. It targets core testing parallelism and reduced test application time by using, as much as possible, existing core interconnects to form TAM ...

RFID (Radio Frequency Identification) technologies have dramatically lowered the cost of data acquisition and have enabled applications to constantly analyze and execute complex operations in real-time. However the technology poses many new challenges ...

High-speed serial network interfaces are gaining wide use in connecting multiple processors and peripherals in modern embedded systems, thanks to their size advantage and power efficiency. Many such interfaces also support multiple data rates, and this ...

Wearable sensors can enhance the relationship between professional downhill skiers and their trainers by revealing information about the athlete's motions--such as force, rotation, or acceleration--that are difficult or impossible for the trainer to ...

We present a specification language and algorithms for the online and offline monitoring of synchronous systems including circuits and embedded systems. Such monitoring is useful not only for testing, but also under actual deployment. The specification ...

Global Position system (GPS) is a positioning system with superior long-term error performance, while Dead Reckoning (DR) system has good positioning precision in short-term, through advantage complementation, a GPS/DR integration provides position data ...

In this paper, we apply the load sharing (LS) mechanism proposed in [1, 2] to HARTS, an experimental distributed realtime system [3] currently being built at the Real-Time Computing Laboratory of the University of Michigan.

Abstract¿BASEMENTTM is a distributed real-time architecture developed for vehicle internal use in the automotive industry. BASEMENT covers application development, as well as the hardware and software that provide execution and communication support. ...

This paper describes an open-source and highly scalable floating-point unit (FPU) for embedded systems. Our FPU is fast and efficient, due to the high parallelism of its architecture: the functional units inside the datapath can operate in parallel and ...

This paper describes the development of a synthesizable SoC platform using OpenCores processor and WISHBONE On-chip bus. The platform includes a OpenRISC 1200 microprocessor, some basic peripherals, such as on-chip RAM, GPIO, UART, debug interface, VGA ...

Code compression, initially conceived as an effective technique to reduce code size in embedded systems, today also brings advantages in terms of performance and energy consumption, due to an increase in the cache hit ratio. This paper proposes the design ...

Earlier performance studies of concurrency control algorithms show that in a disk-resident real-time database system, optimistic algorithms perform better than two phase locking with higher priority (2PL-HP). In a main memory real-time database ...

Embedded system can be defined as information processing systems embedded in larger systems. Digital signal processing and communication algorithms and systems are used in digital communication systems to process information in the digital form. Digital ...

The design and design automation of embedded systems is rapidly emerging as a research area in its own right. It draws from several traditional areas of study such as system specification, modeling and analysis; computer architecture and micro-architecture; ...
