Integrating real-time and general-purpose operating systems into a single embedded device is promising scheme to support both real-time responsiveness and rich functionality with reasonable engineering cost. However, even if the modification for a single combination of real-time and general-purpose operating systems is small, it would be problematic when considering combinations of various operating...
This paper presents a multi-layer power and energy estimation approach for embedded applications and operating systems. The multi-layer methodology is an incremental approach where we consider that energy can be summed over the hyper period of the real-time system. At the first layer, we start by estimating energy and power consumption of standalone tasks. At the following layers, we add energy overheads...
In this paper, the video sever system is designed centered on IME6410. Based on the platform of embedded processor and Linux, after analyzing the internal relations among Video4Linux(V4L) specification, video driver and kernel of Linux, we propose a common method for driver development accord with V4L Specification.
As the rapidly development of embedded systems, it is a challenge for universities to fill the gap between education and industry.

Along with the rapid development of the networking, the number of small company and home office networks are on the increase. A small router which also called SOHO(small office home office) router or IP-sharer becomes the focus of network, because it can share one IP address among some computers in a home network or a small company LAN(local area network) and enable every host to surf the Internet...
Chip-multiprocessors are quickly becoming popular in embedded systems. However, the practical success of CMPs strongly depends on addressing the difficulty of multithreaded application development for such systems. Transactional memory (TM) promises to simplify concurrency management in multithreaded applications by allowing programmers to specify coarse-grain parallel tasks, while achieving performance...
Dynamically reconfigurable hardware allows for implementing systems that can be adapted at run-time according to the needs of the user. This paper presents an architecture that is composed of multiple FPGAs that are connected to an embedded processor. Thus, the architecture is referred to as a multi-FPGA clustered architecture (MFCA). All FPGAs can be partially and dynamically reconfigured to integrate...
There is a strong interest of using cheap and simple Ethernet technology for industrial network. However, traditional way uses a microcontroller (such as Rabbit 2000) in 8 bit mode, which cannot meet the demands of industrial communication. In order to realize communication over industrial Ethernet in 32 bit mode, this paper describes a method using S3C4510B 32 bit RISC microprocessor and uClinux...
