This work aims at improving an existing soft microprocessor core optimized for Xilinx Virtex®-4 FPGA. Instruction and data caches will be designed and implemented. Interrupt support will be added as well, preparing the microprocessor core to host operating systems. Thorough verification of the added modules is also emphasized in this work. Maintaining core clock frequency at its maximum has been the main concern through all the design and implementation steps.

Embedded microcomputers are used in a wide range of applications nowadays. Avionics is one of these areas and requires extra attention regarding reliability and determinism. Thus, these issues should also be born in mind in addition to performance when evaluating embedded microcomputers. This master thesis suggests a framework for performance evaluation of two members of the PowerPC microprocessor family, namely the MPC5554 from Freescale and PPC440EPx from AMCC, and analyzes the results within and between these processors. The framework can be generalized to be used in any microprocessor family, if required. Apart from performance evaluation, this thesis also suggests also a new terminology by introducing the concept of determinism levels to be able to estimate determinism issues in avionics applications more clearly, which is crucial regarding the requirements and working conditions of this very application. Such estimation does not include any practical results as in performance evaluation, but rather remains theoretical. Similar to Automark™ used by AutoBench™ in the EEMBC Benchmark Suite, we introduce a new performance metric score that we call ”Aviomark” and we carry out a detailed comparison of Aviomark with the traditional Automark™ score to be able to see how Aviomark differs from Automark™ in behavior. Finally, we have developed a graphical user interface (GUI) which works in parallel with the Green Hills MULTI Integrated Development Environment (IDE) in order to simplify and automate the evaluation process. By the help of the GUI, the users will be able to easily evaluate their specific PowerPC processors by starting the debugging from MULTI IDE.

This thesis aims to explain the evolution and transformation of the microchip industry. It focuses on the changes and prediction of the future state including its causes and consequences. The analysis starts on the general description of the market and continues through its subjects ending on relationships between them. This serves as a source of information to the prediction in the final part of the thesis. In the beginning the products, which are taken into consideration in this work (namely CPUs, GPUs and APUs), are described. Following this, there is an analysis of the competition environment that defines a structure of the market upon which further work is based. (Three levels; the manufacturer of photolithographic machines, makers of the chips and their designers and OEM and aftermarket subjects.) The penultimate part defines the barriers to entry to this market and three categories are drawn up: economic, technical and geoeconomic, which are applied to every level of the market. Thus all prerequisites to a successful prediction are satisfied. In the last part of the thesis the prognosis is made and defined, along with its assumptions and limitations. In the concluding part of this work the consequences and results are summarized.

This diploma thesis deals with description and subsequent implementation of web interface and control device for selected periphery devices through the use of processor module RabbitCore RCM3700 which is based on microprocessor Rabbit 3000. The importance of web interface based control is currently raised because of higher customers’ claims. Interactivity of these devices contains wide range of services, from simple event communication by text messages to complex driving systems for home which create the base of intelligent house. The customer can choose either the complete and more expensive solution or self-created one. There are two possible ways of creation. The first way is through the use of personal computer. The second one, more complex but also more effective, is by single-chip microprocessor. In this thesis the second one way is used. The module with processor with build-in web interface was used. Description and the way of control are given for this module and also for selected periphery devices, the LCD and digital temperature sensors. At the end the hardware and software part of control device is designed on the basis of gained information. The thesis contains also its brief description.
