2 Administrivia Instructor: Νίκος Μπέλλας Teaching Assistants: Νίκος Κατσαρός Νίκος Ξηρομερίτης Class lectures - Labs: Tuesdays 12-2 pm, Thursdays 9-11 am Location : Lab Α2 Class web page To be used heavily Office: B3.7, 2 nd Floor Phone #: NOTE: Please send me your by the end of the week CE435 - Embedded Systems 2

3 Class objectives We want you to develop skills to design realistic and practical embedded systems and System On Chips (SoCs) This is a practical, hands-on, lab-based course. Theory revolves around the lab and the project The students will work on an innovative project that will involve hands-on design design, configuration, engineering, implementation and testing of a prototype of an embedded system of your choice CE435 - Embedded Systems 3

4 Course requirements Weekly labs (30%) First weekly lab out this week! Term project on design of a microprocessor based embedded system (40%) Final Exam (30%) CE435 - Embedded Systems 4

5 Main idea of the course Lectures and Labs describe how to build a processor based System On Chip Using a Field Programmable Gate Array (FPGA) infrastructure from Xilinx Gradually develop the hardware and software components to implement an application on an SoC and optimize it The labs culminate in a term project which students describe in a design paper and in-class presentation. CE435 - Embedded Systems 5

6 Project Requirements A short project proposal describing in broad terms what you plan to build and how you plan to build it A detailed project design describing in detail the architecture of your project, both hardware and software. This should include block diagrams, memory maps, pseudocode: everything someone else would need to understand your design. An early demo of your project. It should be showing signs of life. This is to make sure you are making reasonable forward progress. A presentation on your project to the class A final project report CE435 - Embedded Systems 6

7 Project Requirements Project has to finish before I give out grades No extensions will be given You can always continue your design after the end of the semester But it WON T affect your grades CE435 - Embedded Systems 7

8 Project requirements Some of the available material for your project: Zedboard (ARM9-Cortex A9 based MPSoC system) To be used in the labs FPGA platform Nexys3 Last generation Spartan6 FPGA Beagle board : An ARM A8-Cortex + TI C64xx DSP processor. Single board computer Used in Netbooks Other accessories Cameras Accelerometers Extensions breadboards CE435 - Embedded Systems 8

9 Prerequisites ECE Οργάνωση Η/Υ ECE Εργαστήριο Ψηφιακών Συστημάτων Good programming skills (in C) Eagerness to learn new things and experiment this is a hands-on class All slides, reference papers, data sheets etc. will be in English CE435 - Embedded Systems 9

10 References There is no required textbook for the class The lectures are based on a variety of resources such as product data sheets, textbooks, papers The tutorial/lab will use FPGAs (Field Programmable Gate Arrays) for both hardware and software Advice: Internet is a vast resource of information on embedded systems. You should use it CE435 - Embedded Systems 10
