This master thesis describes the process of designing an application specific microcontroller. The microcontroller should be used in a demonstrator for a protocol processor. The demonstrator should show the possibilities to access high speed networks with small processor cores. The demonstrator should be able to receive and playback an audio stream. Some of the tasks in the demonstrator should be performed by the microcontroller. It should handle ARP requests, buffer handling and sending audio samples to a stereo codec. Behavioral models for these applications were constructed and used to design the instruction set for the microcontroller. An instruction set simulator was constructed. It was used to verify that the instruction set was sufficient to achieve functional coverage. The micro architecture for the microcontroller was designed and implemented in VHDL. This implementation was verified by simulation. The test vectors used during simulation were mainly randomly generated.

<p>In this bachelor thesis a complete prototype of an industrial vibration measurement platform has been developed. By measuring a number of variables such as acceleration, temperature and speed conclusions can be drawn on machinery health. The aim is to evaluate hardware and software solutions for a possible future product. Based on a requirement specification a proper hardware design has be developed. The hardware consists of a four-layer PCB with an ARM Cortex-M3 microcontroller and about 250 other components. The PCB was designed, assembled, tested and finally housed in a box. Measures have been taken to protect the prototype against external disturbances such as inappropriate supply voltages and transients on the input stages.Software has been written for the microcontroller to perform the various measurements required by the prototype. These include RMS, integration and filtering. Special attention was paid to the latter by implementing filters based on lattice wave digital structures. This structure results in a very efficient implementation. Consideration is taken to be able to generate arbitrary filters independent of the characteristics and design method. To save time the microcontroller implements all the algorithms without any floating point numbers.Furthermore, both hardware and software are adapted for future industrial use. The finished prototype supports a number of communication interfaces in which Modbus (RS-485) and current loop communication can be mentioned.The final result is a very good performing platform with strong future potential.The work was commissioned by the consulting firm Syncore Technologies AB at their office in Mjärdevi, Linköping. The project has, in total, taken 10 weeks and occurred during spring 2010.In this bachelor thesis a complete prototype of an industrial vibration measurement platform has been developed.

This project has been made in cooperation with the company Planeten that have plans to build an indoor playground. The project is about developing a prototype which could rotate and move a ceiling light horizontally and install lightning that can shine with different colors that can be steered. The light motion and color lighting has to be controlled by time or with a button. The work gives an overview of electric motors and motor control, lighting control and various control systems and also the process of designing and developing a mechanical engineering. A moving mechanical unit built with movement technology in the form of belt and pulleys and DC motors that enabled the ceiling lights horizontally and rotating motion. The lighting used, are two different kind RGB LED-lighting. It has also used a control system in the form of microcontrollers to control motors and lighting. At the end of the report presents the results and discussion of the project. / Detta projekt har gjorts i samarbete med företaget Planeten som ska bygga ett lekland. Projektet handlar om att utveckla en prototyp för att rotera och flytta på en taklampa horisontellt samt installera belysning i den som kan lysa med olika färger som går att styra. Lampans rörelse och färgbelysning ska vara tid och knappstyrd. Arbetet ger en överblick av elmotorer, motorstyrning, styrning av belysning och olika styrsystem samt processen att designa och bygga en mekanisk konstruktion. En rörlig ställning byggdes med förflyttningsteknik i form av rem och remskivor och likströmsmotorer som möjliggjorde lampans horisontellt och roterande rörelse. Till belysningen användes två sorters RGB LED-belysning. Dessutom togs det fram ett styrsystem i form av mikrokontroller för att styra motorer och belysning. I slutet av rapporten presenteras resultat och diskussion kring projektet.

This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth. The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle. By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit. The control unit will sense its own direction by a magnetic sensor that works as an electronic compass. The Pan/Tilt-controller will then rotate the link to reach the targets coordinates. Alternatively you can control the position of the link manually by the GUI. The report also discusses the functionality of the sensors and tests have been conducted to determine the accuracy of the control unit. The Pan/Tilt-controller can rotate a link 360º around its own axis and also tilting the link ±90º. The Pan/Tilt-controller can direct a link towards a target with an accuracy of 5º -10º.
