In this paper, A target architecture and interface synthesizer are proposed for processor-embedded codesign. The target architecture has the form of ARM processor based on AMBA. The interface synthesizer automatically generates an interface circuit for the communication between HW and SW. A memory map is used as the communication channel and an interrupt-based interface is applied for synchronized communication between HW and SW modules. In order to verify the function and performance of proposed target architecture and the interface synthesizer, practical test example is applied. Experimental results show the proposed interface synthesizer functioned correctly in the HW/SW codesign environment.

This article surveys techniques and issues related to real time process control system developed for industrial control applications. It covers the system architecture and software engineering issues such as the design of data structures, scheduling of asynchronous task activities, management of shared resources, handling of interrupt and implementing an user friendly man-machine interface. Also problems associated with implementing a real-time system that supports dynamic configuration of data base is addressed.

Ethernet is one of the most successful LAN technologies. Now gigabit ethernet is available in real network and some network interface cards(NIC) supports TCP segment offloading (TSO), IP checksum offloading(ICO), Jumbo frame and interrupt moderation. If we use this features appropriately, we obtain high throughput with low CPU utilization. This paper represents the network performance by varying above features.

Interruption of AC is easier due to natural occuring of zero crossings. In DC, zero crossings is achieved by Forced commutation technique. In this paper an alternative counter voltage(ACV) DC Hybrid Circuit breaker(DC-HCB) is modeled using EMTP/ATP tool, Results show that, ACV DC-HCB can interrupt DC with in 5ms with a source voltage of upto 1 KV.

Low voltage circuit breakers which interrupt rapidly and raise the reliability of power supply are widly used in power distribution systems. In the paper, it was investigated how much Interrupting capability was improved by correcting the shape of the contact system in molded case circuit breaker(below MCCB), Prior to the interrupting testing, it was necessary for the optimum design to analyze magnetic forces on the contact system, generated by current and flux density. This paper presents both our compuational analysis and test results contact system in MCCB.

This paper describes the design and implementation of a high-speed navigation computer to achieve precision navigation performance with Strapdown INS. The navigation computer inputs are velocity and angular increment data from the ISA at the signal of the 2404Hz interrupt and performs the removal of gyro block motion and the compensation of high dynamic errors at the 200Hz. For high-speed and high-accuracy, the computer consists of the 68040 micro-processor, 128k Memories, FPGAs, and so on. We show that the computer satisfies the required performance by In-Run navigation tests.
