In this paper, we propose a virtualization architecture for the multi-core embedded system to provide more system reliability and security while maintaining the same performance without introducing additional special hardware supports or having to implement complex protection mechanism in the virtualization layer. Virtualization has been widely used in embedded systems, especially in consumer electronics,...
Virtualization of embedded systems has recently been in the spotlight especially because of the numerous advantages it can bring. Among these, the improvement of software design quality can be highlighted, since legacy software can be reused along with newer applications, easing newer and older systems' integration. Also, security concerned systems can enjoy the gains of virtualization: two Operating...
A virtualization layer makes it possible to compose multiple functionalities on a multi-core processor with minimum modifications of OS kernels and applications. A multi-core processor is a good candidate to compose various software independently developed for dedicated processors into one multi-core processor to reduce both the hardware and development cost. In this paper, we present SPUMONE, which...
High-performance embedded systems require the execution of many applications on multicore platforms and are subject to stringent restrictions and constraints. The ACTORS project approach provides temporal isolation through resource reservation over a multicore platform, adapting the available resources on the basis of the overall quality requirements. The architecture is fully operational on both...
Embedded learning applications in automobiles, surveillance, robotics, and defense are computationally intensive, and process large amounts of real-time data. Systems for such workloads have to balance stringent performance constraints within limited power budgets. High performance computer processing units (CPUs) and graphics processing units (GPUs) cannot be used in an embedded platform due to power...
With increasing demand for higher performance under limited power budgets, multicore processors are rapidly becoming the norm in today's embedded systems. Embedded software constitutes a large portion of today's systems and realtime software design on multicore platforms opens new design challenges. In this paper, we introduce a high-level, host-compiled multicore software simulator that incorporates...
Today's high performance embedded computing applications are posing significant challenges for processing throughout. Traditionally, such applications have been realized on application specific integrated circuits (ASICs) and/or digital signal processors (DSP). However, ASICs' advantage in performance and power often could not justify the fast increasing fabrication cost, while current DSP offers...
The host-multi-SIMD chip multiprocessor (CMP) architecture has been proved to be an efficient architecture for high performance signal processing which explores both task level parallelism by multi-core processing and data level parallelism by SIMD processors. Different from the cache-based memory subsystem in most general purpose processors, this architecture uses on-chip scratchpad memory (SPM)...
This paper presents the design and implementation of an embedded system kernel, namely Zinix, with functional modularity for multiprocessor platforms. Zinix supports system configuration of both homogeneous and heterogeneous multiprocessors with shared memory. Its design is based upon the concept of micro-kernel with emphasis on modular functionality and reusability in order to be flexible and suitable...
Multi-core processors are being increasingly adopted for embedded systems because they improve performance, power consumption and lower development cost. Composing multiple operating systems on a multi-core processor enhances the reusability of software when developing rich functional embedded systems. Multiple OS environments enable the product to use two versions of an operating system at the same...
In Recent years embedded world has been undergoing a shift from traditional single-core processors to processors with multiple cores. However, this shift poses a challenge of adapting legacy uniprocessor-oriented real-time operating system (RTOS) to exploit the capability of multi-core processor. In addition, some embedded systems are inevitably going towards the direction of integrating real-time...
The heterogeneity of the state-of-the art embedded systems containing multicore platforms requires the application design flow to enable the creation of parallel applications using multiple Models of Computation. Components of such systems may interact in various ways, often using ad hoc methods. However, due to the poor reusability and analysability of ad hoc solutions, more structured approaches...
Many SoCs adopt multicore architectures. As a result, embedded programmers are also facing the challenge of parallel programming. We propose a parallel skeleton library that can be used on embedded multicores. Our library is implemented in standard C++ using template features. We propose two parallel skeletons to support common program patterns on multicores. In our skeleton library, programmers can...
Embedded media applications have traditionally used custom ASICs to meet their real-time performance requirements. However, the combination of increasing chip design cost and availability of commodity many-core processors is making programmable devices increasingly attractive alternatives. Yet for these processors to be successful in this role, programming systems are needed that can automate the...
The embedded multi-media terminal was designed and developed, which using SAMSUNG Corporation's S3C2410 chip as core processor. Firstly, an embedded Linux operating platform has been built in the UP-NETARM2410-S target machine according to system requirements, which includes boot-loader, kernel, file system, and related device drivers. Then the upper computer equipped Qt/Embedded as SDK(Software Development...
It is common nowadays that consumer embedded system products are built on platforms with System-On-a-Chip (SOC) in which two or more processor cores, which are not necessarily of the same type, are put into a single chip and form the architecture of Chip-level Multi-Processor (CMP). Although such platform is capable of achieving high performance at relatively low cost, the system architecture of CMP...
In this paper, the embedded web server, which take Samsung corporation's ARM9-S3C2440AL processor as core, is designed, it's operating system is Linux, the system hardware architecture is presented. Then the process of the Linux operating system being transplated on ARM is introduced. The realization of Boa and dynamic interaction between browser and the embedded system by using CGI are especially...
At present, study on open numerical control (NC) system is increasingly getting attention. Most of these studies concentrated their aims at realizing the open system structure based on PC or IPC (industrial personal computer). Few involved the category of embedded NC (ENC) system, but expectant goals could not be achieved at the performance of real time (RT) and reliability of system response. In...
Object detection is an important function for intelligent multimedia processing, but its computational complexity prevented its pervasive uses in consumer electronics. Cost-effective & energy-efficient computations are now available with various innovative multicore architectures proposed for embedded systems. However, extensive software optimizations are needed to unravel the inherent parallelisms...
Queues are one of the most commonly used data structures in applications and operating systems. Up-and-coming multi-core processors force software developers to consider data structures in order to make them thread-safe. But, in real-time systems, e.g., robotic controls, parallelization is even more complicated as such systems must guarantee to meet their mostly hard deadlines. A considerable amount...
