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...
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 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...
Cell Broadband Enginetrade is a multi-core system on a chip and is composed of a general-purpose power processing element (PPE) and eight synergistic processing elements (SPEs). Its high computational performance is achieved mainly through the SPE's processing power. New high-speed NICs such as 10-Gbps Ethernet require significant amounts of processing power. Even the full processing power of PPE...
