AUTOSAR is a partnership of automotive manufacturers and suppliers working together to develop and establish a de-facto open industry standard for automotive software architectures. In the AUTOSAR architecture, the runtime environment is at in the heart of the AUTOSAR architecture to provides the infrastructure services that enable communication between software components and between software components and basic software components. The RTE generator is an automated generation tool for AUTOSAR specification based RTE according to the ECU configuration. It generates communication API function for the software components and the basic software components like OS and COM of the application. The availability and the accuracy of the RTE generator are important for the automobile software which is based on AUTOSAR architecture, this paper proposes an architectural design of the RTE generator for auto-generation of the AUTOSAR based RTE.

A conventional environment adaptation for robust speech recognition is usually conducted using transform-based techniques. Here, we present a discriminative adaptation strategy based on a multi-condition-trained model, and propose a new method to provide universal application to a new environment using the environment's specific conditions. Experimental results show that a speech recognition system adapted using the proposed method works successfully for other conditions as well as for those of the new environment.

At the present time, multimedia chip, internet application, and network equipment is designed by using ARM core. Because it has a good debugging, software compiler and needed low power. We must process a data coding to send a multimedia data by real time. So need to connect software and hardware algorithm. In this research, We design interface for ARM9/AMBA based board using VHDL for these function implementation. The board is used the ARM company´s ARM940T for software function implementation and Xilinx company´s Virtex E2000 for hardware function algorithm. The various hardware algorithm (ME,ME,DCT) block for performance can be implemented on this system.

In this paper, we implemented the Android NDK porting application with Eclipse(JDK) ADT and TinyOS 2.0. TinyOS and Cygwin are component based embedded system and an Open-source basis for interfacing with sensor application from H-mote. Cygwin is a collection of tools for using the Linux environment for commercially released with x86 32 bit and 64 bit versions of Windows. TinyOS-2. x is a component based embedded OS by UC Berkeley and is an Open-source OS designed for interfacing the sensor application with specific C-language. The results of Android porting experiment are described to show the improvement of sensor interfacing functionality under the PXA320 embedded RTOS platform. We will further more develop the software programming of Android porting under Embedded platform and enhance the functionality of the Android SDK with mobile gaming and kernel programming under sensor interfacing activity.

The article discusses the application of the IoT concept in the sensitive field of medical devices on the example of a developed prototype of a mechanotherapeutic simulator. Mechanotherapy is a complex of therapeutic, preventive, and restorative exercises conducted using simulators, specially designed for developing movements in individual joints. Mechanotherapy is used for the early and painless restoration of joint mobility, to prevent complications associated with prolonged immobilization of the injured area of extremities. Using the mechanotherapy simulator allows developing the joint painlessly, which accelerates the metabolism in the injured area, and soft tissues are restored to normal. The article provides information about the electronic components that ensure the wireless operation of the device and describes in detail the applied software as well as the client application for a mobile device.

In this paper, we introduce new FTL(Flash Translation Layer) driver algorithm that tolerate the power off errors. FTL driver is the software that provide the block device interface to the upper layer software such as file systems or application programs that using the flash memory as a block device interfaced storage. Usually, the flash memory is used as the storage devices of the mobile system due to its low power consumption and small form factor. In mobile system, the state of the power supplement is not stable, because it using the small sized battery that has limited capacity. So, a sudden power off failure can be occurred when we read or write the data on the flash memory. During the write operation, power off failure may introduce the incomplete write operation. Incomplete write operation denotes the inconsistency of the data in flash memory. To provide the stable storage facility with flash memory in mobile system, FTL should provide the fault tolerance against the power off failure. SSR (Simple Sector Remapper) is a fault tolerant FTL driver that provides block device interface and also provides tolerance against power off errors.

For such large-scale software as for operating a switching system, the use of real-time databases is essential for data exchanges among various functions and their data processing. Under the environment of developing the DBMS software for a switching system, the application program including database manipulations is first developed on a host computer and then the developed program is loaded into a switching system for its tests. To make it possible for DBMS manipulation software to be developed on a host computer rather than a switching system itself, we developed a host-based DBMS simulation system(HDBMS). In this paper we presented the roles and functions of HDBMS, its system structure, and the technical details for implementing HDBMS.

Grid Computing has enabled enormous amount of computational jobs by connecting distributed computing resources. This technology has developed and widely used in various fields. Previous researches usually focused on how to efficiently manage and use the grid resources. However, there was not enough tries to understand and manage information of application softwares in a well-defined structure. Therefore users in application domain need to how about grid deeply to identify and describe the resource requirements matching for each jobs. We introduce a semantic grid management system based on application ontology to overcome this problem. We design and implement the ontology to store various information of the applications. With the ontology, this system can infer the resource requirements from input parameters and input data of the application software and automatically assign appropriate resources by matching the requirement. Also it can transform the information to other forms which grid middlewares can handle. We apply the system to construct an analysis environment of bioinformatics and compare it with other grid systems to explain usefulness of the system.
