HTML5 Smart Virtual Machine is a virtual machine based solution to executing contents on various platforms such as PC, Smart TV, and mobile devices by web browsers that support HTML 5. This HTML 5 SVM has an advantage as a virtual machine, but the VM based execution method raise a problem on executing performance. This paper proposes an offloading method to solve this performance problem by the performance enhancement of the HTML5 SVM with cloud system. By the proposed method, HTML5 SVM is enhanced its performance extremely using cloud server side execution on complexed and time consumed functions.

Every platform used in the development of smart phone contents has a unique development environment. The need for platform-specific methods and languages entails extra development costs when content is created for a number of platforms. The Smart Cross Platform is the virtual machine solution that supports various programming languages and platforms, and its aims are to support programming languages and smartphone platforms such as Android and iOS. Various contents that developed by supported language on the platform can be execute on Android and iOS platforms at no additional cost. But, can assume that optimization of executed code is very important because act thing which VM is slow than that process by real processor. In this paper, we deal with code optimizer generating techniques to automatically generate an optimizer for virtual machine.

Recently, the computing environments are developing to the IoT services which exchange a lot of information using various and heterogeneous devices that always connected on networks. Since the data communication and services take places on the various devices including not only traditional computing environments and mobile devices such as smartphone but also household appliances, embedded devices, and sensor nodes, the security requirements is getting more important at this point in time. In this paper, the compiler with secure software concept was proposed to develop the secure applications for IoT services.

A distributed algorithm for task assignment (TA) is one of the most important issues in multiple unmanned aerial vehicles (UAVs) environment. Most studies are the efficient task assignment decision between UAVs for solving specific problems. In this paper, we will propose an approach for handling faults in communication while multiple UAVs for cooperation and coordination. We will also discuss a fault tolerance scheme for the procedure.

In this paper, we will introduce the JavaScript compiler for the SCP (Smart Cross Platform) to expand the SCP's coverage. The SCP is the virtual machine based solution that supports various programming languages and platforms, and its aims are to support programming languages like ISO/IEC C++, Java and Objective C and smartphone platforms such as Android and iOS. By adding the new compiler to SCP's compiler collection, SCP can be support the new type of the programs such as web applications written by JavaScript.

The debugger, a tool to revise the error existing in programs, provides the functions including controlling the program execution, displaying the state information and modification. This paper presents the interface to support a debugger on smart virtual machine (SVM) through analyzing the GDB for the existing native programming environment and the java debugger for the virtual machine environment.

This paper presents the priority scheduling for the thread model of Smart Virtual Machine (SVM). The existing SVM have assured the execution time to all created threads equally, so that it was not able to distribute time in accordance with the importance of threads. We designed scheduling technique which suits to the characteristics of SVM through analyzing the existing priority scheduling.

Although the executing program on virtual machine environment has an attribute of platform-independence in general, it shows low speed performance and it is unable to implement platform independency directly. Also it has a disadvantage that the library and program written in native language cannot be reused. This paper presents the research about providing a native interface of Smart Virtual Machine (SVM). The paper also presents the operating mechanism of Java Native Interface (JNI), the interface generator, the interface definition language and so on to account for the native interface regulation.

The recent computing environment is developing to the IoT services which exchange tremendous amount of information as the variety of devices are connected to network all the time. Since the data communication and services take places on the variety of devices including not only traditional computing environment and mobile devices such as smartphone but also embedded devices and sensor nodes, the security requirements is getting more important under this environment. This paper presents the weakness inspection mechanism to implement secure software on the IoT environment.

In this paper, the WIPI-to-iOS automatic mobile game converter was designed to automatically translate mobile game contents from the WIPI plat- form to the iOS platform for smart phones. Through the WIPI-to-iOS converter, resources such as images and sounds can be converted, APIs can be converted using a platform mapping engine with wrapper functions. These and all other content conversion functions were examined. Test results indicate that the graphics, image output, sound output, and other functions of converted iOS platform games were equivalent to those of the WIPI platform games before conversion.

In this paper, we will deal with the reversing technique to verifying the symbol table in Objective C compiler. The proposed technique reconstructs inputted Objective C program segments - declarations part - by using infor- mation of the symbol table inserted during the process of declaration analysis phase of the Objective C compiler, and therefore we can verify the complete- ness of symbol table design and validity of information inserted in the symbol table.

The Smart Cross Platform guarantees content compatibility on vari- ous smart devices and supports numerous programming languages which is a solution to increase development productivity. The SVM (Smart Virtual Ma- chine) is the core virtual machine of the smart cross platform. In this paper, a technique which allows previous SVM which operates on smart devices to op- erate on web environment is introduced. In the whole design and implementa- tion of the SVM which operates in the web based environment, this paper fo- cuses on the interpreter which is a method to execute the contents.

The SVM (Smart Virtual Machine) is a stack based platform independent virtual machine solution, loaded on smart devices, which allows dynamic application programs to be downloaded and run platform independently. The SIL (Smart Intermediate Language) has been designed as a standard model of virtual machine codes for ordinary smart phones and embedded systems. It is a set of stack based commands which has the characteristics of language independence, hardware independence and platform independence. In this paper, we present the platform independent virtual machine code based the compilers for the SVM. This makes the existing mobile contents to be ported quickly, and to be executed to a different platform.

iOS and Android represent mobile platforms each supporting individual execution environment, development tools and development methodology. Applications and contents developed in each platform inevitably have exclusive properties in the other platforms. Therefore, generally it is not possible to execute a mobile application on a different platform. In order to provide service to multiple platforms by portability, additional costs and development period is required. Particularly, the lifespan and development duration of mobile applications are becoming shorter at this point in time. In this paper, Smart Cross Platform's content execution component, Smart Virtual Machine based on an independent neutral language was designed and implemented to be run in iOS.
