Повний текст джерелаTest och bedömning av derivatberäkningsarkitekturer som använ-der OpenMDAO och dess tillämpning i ett verkligt problem för flygplansoptimering. Optimeringsproblemen är utbredda i vardagsliv och ingenjörsvetenskap. I ingenjörsoptimeringsteknik modelleras problemen vanligtvis med en objektiv funktion. För att lösa dessa slags ingenjörsoptimeringsproblem finns två huvudkategorier av optimeringsalgoritmer: gradientbaserade algoritmer och gradientfria algoritmer. Vi kommer att fokusera på gradientbaserade algoritmer där beräkningen av derivatan är ett kritiskt steg i processen. I denna avhandling presenterar vi fem olika metoder för att beräkna derivatan. Dessa är så kallade Finita differensmetoden (FD), komplexa stegmetoden (CS), den automatiska differentieringsmetoden (AD) och två analytiska metoder - direkt och så kallade adjoint - metoder. Vi demonstrerar hela proceduren med dessa metoder på testfall och visar deras genomförande med hjälp av NASA:s mjukvara Open Source Framework MultiDisciplinary Analy-sis and Optimization (OpenMDAO). Slutligen testar och utvärderar vi deras prestanda i OpenMDAO genom att modellera ett verkligt problem med flygblad.

Because development of multimedia platform is flourishing, the consumers’ demands for vedio, audio, image and 3D applications on the hardware platform increases constantly. This class of product requires high performance processing.In order to satisfy the consumers’ demands, a variety of hardware solutions has evolved. One of the chanllenges with all of these architectural variants is to develop efficient code. In general, these hardware platforms shall provide compilers. But it is difficult to bring the abilities of the hardware into full play only via compiler. When much software will be ported to new platforms, the codes of softwares must be re-written and optimized. The effect of this inefficiently in implementation is to delay the introduction of new products, increase development costs and reduce product quality. Eventually, it will slow down innovation and development in the multimedia domain at a time when market demand is growing. In order to solve this issue, the OpenMAX�� Working Group has been formed by the Khronos Group, to define a set of standard, open APIs for multimedia applications. The goal of this open standard is to reduce the cost and complexity of porting multimedia software to new processors and architectures. The advantage of this open standard is to be compatibly with multimedia applications on different platforms. The comman functions that different programs use will not be re-written. It will be possible for software and hardware developer community to focus on differentiating their products. The goal of this paper is to use OpenMAX�� IL APIs to integrate MP3 decoder library and ALSA library into player developed via these APIs on dual-core SoC platform. We will research the portability stressed by OpenMAX�� through the system implementation, and to observe the overheads of implementation via OpenMAX�� IL API. Eventually, to estimate what effects of software performance were caused by using OpenMAX�� IL APIs.

With the arrival of the multimedia, and the improvement of IC industry, the functions of the new generation PMP (portable Media Player) is becoming stronger and stronger. It is no doubt that the powerful functions of multimedia are expected. There are many kinds of multimedia, including music/sound effect, audio, picture (static image), video (dynamic image), 2D/3D animation, etc. The most mobile multimedia devices have several abilities. First, they support H.264, MPEG-4, MP3, VC1, and AAC which are the main stream of image and audio codec. Second, they support the standard of wireless communication, such as GSM, GPRS, 3G, or WiMAX on the cell-phone platform. These technologies mentioned above need many kinds of process ability and more complicated design of circuit. If each of these technologies is designed individually, it is definitely impossible to reach the goals of small size and the portability. Thus SOC with integration ability is applied on the mobile media device extensively. However, because these devices need the cooperation on hardware and software, two important issues about efficiency and energy saving are worth of being considered. The most popular PMP architecture is multi-core processor that has one MPU (Main Processor Unit) plus one or more DSP (Digital Signal Processor). OpenMAXTM is a unified standard released by Khronos group. There are two important interfaces. One is DL (Development Layer) and the other one is IL (Integration Layer). The major advantage is that these two interfaces can cross platforms and accelerate the performance of hardwares when the users and programmers process multimedia codec. The main motivation of this thesis is to accelerate the performance of processing multimedia. The platform of the experiment was called PACDSP platform which was developed by ITRI. The testing was under the environment of PACISS simulator. The multimedia codec adopted H.264 decoder, which followed OpenMAXTM DL standard. Then the author designed one library by PACDSP assembly code and implemented the algorithm as well as optimization. Therefore, the upper users can call this designed library to communicate with the PACDSP hardware more conveniently.

With the growing development and popular exercise of wireless network, multimedia applications provided on mobile devices have increased gradually, including voice, music, image, video, and the interaction by the communication network. It is now an important issue to accomplish a system architecture with multi-processors to deal with different requests from multimedia applications. Today, heterogeneous dual-core architecture has been a popular research and implementation on mobile devices. It refers to a Main Processor Unit(MPU) cooperates with a Digital Signal Processor(DSP), which takes charge in complex numerical computation procedures, to meet the requests of communication and multimedia applications on mobile devices. When porting multimedia applications on different platforms, developers usually need to re-design and re-write those codes, which will be time-consuming. To solve this problem, the Khronos Group has defined a set of standards and Application Programming Interfaces (APIs), called OpenMAX(TM), to provide portability for multimedia applications. With two main interfaces: Integration Layer and Development Layer, OpenMAX(TM) APIs enables effective development of media codec implementations, regardless of underlying hardware architecture[4]. The main research of this thesis is to implement H.264 baseline profile decoder on a Dual-Core platform, combined with an ARM processor as the MPU, and a PACDSP developed in STC of ITRI. We adopt PACDSP Assembly language and follow the definition of OpenMAX(TM) DL to design a set of libraries for developers to easily invoke H.264 decoder functions. Then we discuss the influence of function allocation using OpenMAX(TM) definition, and analysis the efficiency of the H.264 decoder on both Single-Processor and our Dual-Core platform. Finally, we discuss the impact that the communication mechanism between MPU and DSP has brought to the system implementation.
