The agent system for managing various equipments constituting communication networks is usually started to be developed after completing real resources or can be developed using network management platform independent from real resources. In this paper, we design real resource simulator which can perform in advance the function of real resources without real resources. The real resource simulator performs the role of automatically generating specific attribute value and informing it according to the specified random function. Moreover, in this paper, we design E-GDMO grammar in which the grammar for simulation is added to the existing GDMO grammar and its E-GDMO compiler to perform real resource simulator.

In this paper, we propose a RRS(real resource simulator) that supports the development and operational test of network management system before the development of real resources. The components of the RRS are the MOT(Managed Object Table) that holds the current status information of real resources, the SDT(Simulation Data Table) that holds the characteristics of real resources defined by user, the support functions that generate the random values and random interval values, the scheduling table that holds the sequence of events, and the main kernel. Users can set up behaviors of the RRS by extended-GDMO description. We present the structure of our extended-GDMO compiler and activities of RRS. We also show the interaction between user and the RRS, interaction between the RRS and the agent, and interaction among the NMS, the agent and the RRS.

This paper presents the technique to develop an operational flight program(OFP) of avionic system computer(ASC) which integrates the avionics control, navigation and fire control and provides informations for flight, navigation and weapon aiming missions. For the development of the OFP of ASC, two i960KB chips are used as central processing units board and standard computer interface library(SCIL) which is built in house is used. The Irvine compiler corporation(ICC) integrated development environment(IDE) and the programming language Ada95 are used for the OFP development. We designed the OFP to a computer software configuration item(CSCI) which consists of to three parts for independency of software modules. The OFP has been verified through a series of flight tests. The relevant tests also have been rigorously conducted on the OFP such as software integrated test, and ground functional test.

This paper proposes a SOC platform which is eligible for education and application SOC design. The platform, fully synthesizable and reconfigurable, includes the OpenRISC embedded processor, some basic peripherals such as GPIO, UART, debug interlace, VGA controller and WISHBONE interconnect. The platform uses a set of development environment such as compiler, assembler, debugger and RTOS that is built for HW/SW system debugging and software development. Designed SOC, IPs and Testbenches are described in the Verilog HDL and verified using commercial logic simulator, GNU SW development tool kits and the FPGA. Finally, a multimedia SOC derived from the SOC platform is implemented to ASIC using the Magnachip cell library based on 0.18um 1-poly 6-metal technology.

The complicated embedded system for multi-tasking requires RTOS(real-time operating system). It uses the optimal OS and processor to each embedded system on the heterogeneous development environment. This paper is proposed to use UML profile of OS API and Processor Configuration, instead of cross-compiling for developing the heterogeneous embedded system. This reduces the development time and cost through generating the automatic source code with the profile information of each embedded system. We generate and port the code after modeling the two heterogeneous real time operating systems (brickOS and uC/OS-II) and the processors (Hitachi H8 and Intel PXA255) with our proposed profile of the heterogeneous embedded system.

Retargetability is typically achieved by providing target machine information, ADL, as input. The ADL are used to specify processor and memory architectures and generate software toolkit including compiler, simulator, etc. Simulator are critical components of the exploration and software design toolkit for the system designer. They can be used to perform diverse tasks such as verifying the functionality and/or timing behavior of the system, and generating quantitative measurements(e.g., power energy consumption) which can be used to aid the design process. In this paper, we generate the energy consumption estimation simulator through ADL. For this goal, firstly, we describes the energy consumption estimation and monitoring informations on the ADL based on EXPRESSION. Secondly, we generate the energy estimation and monitoring simulation library and then constructs the simulator, RenergySim. Lastly, we represent the energy estimations results for MIPS R4000 ADL description. From this subjects, we contribute to the efficient architecture developments and prompt SDK generation through programmable experiments in the field of mobile software development.

Aspect-Oriented Software Development is new software development method. It has many advantages related to software performance, maintenance and repair. Also it offers modularization method to a existing programming language for secondary function such as security and fault tolerance. But the present problem is that we have to use new aspect-oriented programming language. Further more when we apply Aspect to legacy system, we have to recompile the source code in order to build software system based on AOSD. In this paper, we propose and design Connector that can be composed with Aspect in legacy system dynamically. To elaborate this work, we use the information of operations about Core and Aspect, and the information of pointcut described with XML. We validate that the proposed Connector has features such as no need of new compiler, no recompilation and no modification of legacy system through case study.

Systematic telecommunication network management is essential for operating large-scale integrated networks which consist of various network components manufactured by different vendors. ISO and ITU-T recommend the CMIP-based TMN architecture for this purpose. TMN uses GDMO for the definition of managed objects, and various GDMO compilers have been developed. However, the development of management objects by using these compilers is still a difficult task. In this paper, we present a GUI-based managed objects development environment, MODE. MODE divides managed object codes by system independent code(SIC) and system dependent cede(SDC). By providing development environments for SIC and SDC, MODE can ease the development of managed objects. To show the efficiency of MODE, we develop the managed objects of an ATM switch in MODE.
