Due to the rapid advancement of VLSI technology, functions of multimedia systems (e.g. MP3, image processing etc,) become more complex nowadays. Therefore, more complicated system architecture and powerful computing ability are required to attain real-time process. In order to fulfill the requirement of cost and efficiency, multimedia systems usually consist of processors, ASICs and other various components. Diverse real-time functions of multimedia system can be implemented via co-operation of these components. However, these components have the differences in area, efficiency, and cost. Accordingly, it is necessary to establish a useful method and tool to decide better system architecture. ¡@¡@The main objective of the thesis is to develop a decision tool of system architecture. Given the system specification and constraints of a multimedia system, it can quickly decide a good system architecture to satisfy the constraints in accordance with the system specification . Except for partitioning various functions and mapping functions to hardware components, the decision tool must implement scheduling and pipelining to fulfill resource constraints and reach the real-time requirement. A great deal of time and cost for implementing the multimedia system can be reduced by careful scheduling and pipelining. Besides, owing to the pressure of time to market in system development, we propose a series of design flow to speed up the design process. All decision tasks in the flow are finished by automatic or semi-automatic method to reduce the exhaustion of manpower and time. Finally, we make experiments with the proposed tool on several multimedia systems. The results show that the automatic process can conform to constraints which set up by system specifications and ensure the accuracy of the process.

In the last years, with more and more transistors can fit into a chip, the growth the IC design complexity is fast and original design flow can¡¦t cater for designers. Therefore, so many people promote to integrate the system into a single chip gradually with the last technology using the concept of hardware/software co-design. In this thesis, we use the hardware/software co-design concept to build a simple video codec from system level and implement it on the ARM¡¦s SOC platform. We focus on the hardware/software co-ordination. Because we use the platform-based design method, the build hardware/software modules can be used in the similar architecture on the ARM platform In our Video codec system, discrete wavelet transform(DWT) and RGBtoYCbCr are the most timing-consuming parts. Since DWT has inherent scalability and excellent features of energy compaction, it has been applied widely in the various image compression systems. We adopt the 5-3 filter lifting-based DWT in the hardware part of our system and design three different lifting-based DWT architectures by using the high level synthesis concept to optimize the hardware utilization and speed. In the premise of not increasing memory access times and additional processes of software, we overcome the boundary extension of DWT and verify it by means of FPGA after combining it with the RGBtoYCbCr hardware architecture. Finally, the hardware part is integrated with the other part implemented by software, we build a completely video encode system on the ARM SOC platform using the hardware/software co-design.

MP3 compression format is essential categorized one of the MPEG (Moving Picture Experts Group) standards for digital audio compression nowadays. For its superiority and convenient,MP3 has been widely used in multimedia player and storage application. In this thesis, we use software/hardware co-design methodology to design the MP3 player system. In addition, system level scheduling is adopted to arrange the execute time of SW and HW and significantly reduce the hardware cost under the construct of real-time processing. We can obtain fewer extra hardware cost while attaining the goal of real- time playing system. In order to perform software/hardware partitioning, simulate and analyze the MP3 application program to find out the critical parts with high time complexity and regular computation. These parts with high time complexity, e.g. IMDCT and Poly Phase synthesis filter bank, then are implemented by hardware to achieve better system performance. We use high level synthesis concept to optimize the hardware part and integrate software and hardware¡Asuch that communication between software and hardware can be performed smoothly. Finally, MP3 player system is using verified by hardware¡Bsoftware co- verified methodology on an SoC development platform. In order to build a complete verification environment, we attach extra input and output interfaces to the SoC development platform, e.g. the network card and sound card. Write some driver to drive related peripheral device. Since OS is conducive to the operations between software and hardware, Linux OS is ported to the SoC platform to manage software and hardware resources and drive the peripheral devices.

This thesis reacts to the still poorly mastered area of requirements analysis in the development of software, which shows that incorrectly defined requirements are one of the major causes of failure of software projects. The thesis deals with the techniques for gathering requirements, for example the use of requirements workshops as an approach, where a number of various stakeholders under the guidance of a facilitator create a defined output and collectively shape the requirements for SW. Organizing similar workshops is an intensive activity in which it is necessary to consider many aspects; these are discussed in the theoretical part of the thesis. The practical outcome of this work is a methodological framework purposed as a guideline for organizing a specific workshop focused on understanding the problem areas and solutions, identifying stakeholders and the scope of the project, where the problem is viewed from the perspective of the overall context and detachment, which is essential in the early stages of the software project. The workshop was designed and implemented during a university course Software Project and adapted the MMSP methodology, which is used in the course.

The goal of this thesis is to research to role of data profiling in data quality management and the quality of existing data profiling SW tools. The role of data profiling was based up an analysis of the general methodology of approach to the management of data quality. I've compiled an own methodology for the analysis of data profiling tools. This methodology focuses on three main aspects: Technical requirements, User friendliness and Functionality. Based on the methodology the best SW solution for data profiling was chosen. General shortcomings of tested SW tools were also analysed.

There are numerous emerging companies creating interesting and often unique projects in the 21st century. These companies frequently operate in a new, rapidly changing sector. These companies may face an insufficient supply of standardized information software, capable of supporting the business. On the contrary, an individual application software (made from scratch) might not be an option for the companies due to lack of finance to fund its development. Moreover, such SW may not be suitable for companies, especially in a situation when the company starts business activities in a new field, where all the business processes, hence the software requirements, emerge after many test runs and trials. In theory, this thesis focuses on possible solutions to this problem and in practice examines one specific software solution using an example of a property management company Property Rentier s.r.o. (hereinafter PR) which offers complex management services for recreational homes and short-term rental properties, especially using an Airbnb platform. PR has currently been confronted with a decision to make, whether or not to restructure its software solution and its architecture or keep its own and merely keep expanding it. The main goal of this thesis is to analyze and summarize the current processes of the selected company, describe how it is being supported by IT/ICT and, based on these findings, evaluate and recommend further measures regarding restructuring of the companys IT systems. The thesis output is meant for the PR company as well as for any start-up companies as a supportive material which should help ease its struggle making decisions about software development or its purchase.

Foram avaliadas as atividades farmacológicas antioxidante, antimicrobiana e a toxicidade dos extratos etanólico (EE) e aquoso (EA) de folhas, além da descrição dos constituintes de seu óleo essencial e sua atividade antimicrobiana. Para avaliação da atividade antioxidante desta espécie, realizou-se ensaio espectrofotométrico baseado no princípio de redução do radical livre 2,2-difenil-1-picrilhidrazila (DPPH). Para avaliação do potencial antimicrobiano, o ensaio da Concentração Inibitória Mínima (CIM), seguido da Concentração Bactericida Mínima (CBM) e Concentração Fungicida Mínima (CFM). A CIM foi avaliada pela técnica de microdiluição em caldo, enquanto que a CBM e CFM foram realizadas em placas de Petri. Ainda, verificou-se a atividade tóxica, através da utilização da Artemia salina (L.). Na investigação da atividade antioxidante, obtiveram-se inibições do radical livre DPPH nas concentrações de 0,1 mg. mL-1 a 0,005 mg. mL-1 para os extratos etanólico (EE) e aquoso (EA) das folhas, onde através da análise estatística ANOVA, seguida de Student-Newman-Keuls, demonstrou a potencial atividade antioxidante dos extratos ser superior aos padrões testados. Na atividade antimicrobiana, obtiveram-se valores de CIM na faixa de 2,5 mg. mL-1 a 1,25 mg.mL-1 para o EE, enquanto que para EA não verificou-se atividade. No ensaio da letalidade da A. Salina o EA não foi verificada toxicidade, e o EE apresentou, devido ao seu baixo valor encontrado no cálculo da regressão linear da DL 50, apresentou toxicidade moderada. Do óleo essencial, 97,3% dos seus constituintes foram identificados por cromatografia gasosa e espectrometria de massas, tendo como constituintes majoritários o β-elemeno (31,7%) e o α-humuleno (28,2%). A avaliação antimicrobiana, do óleo essencial, foi realizada por bioautografia, apresentando atividade bacterida para Staphylococcus aureus, Staphylococcus epidermidis e Escherichia coli e Pseudomonas aeruginosa, já para os fungos a atividade foi menor.
