Computer Architecture II 1 Computer architecture II Professor: Florin Isaila Professor Coordinator: Felix Garcia Caballiera

Computer Architecture II 2 Administrative stuff: Office hours Florin Isaila Office: 2.1.D05 Wednesday By appointment Francisco Javier García Blas Office: 2.2. A26

Computer Architecture II 3 Administrative stuff 3 independent parts: theory, projects and short practical assignments.In order to pass the class the grades of theory and of the project parts must be greater or equal than 5 and the final grade must be greater or equal than 5 Final grade: Total = Exam*0,5 + Project*0,25 + Practical assignments*0,15 + Class participation*0,10 If a student passes only one of the theory or the project in June session, the grades will be kept for the session in September. More information: webpage: For any doubts please contact the professors during the office hours or by .

Computer Architecture II 4 Administrative stuff: exam 2 hours During the exam you can not use any additional material (books, notes). Cheating = failure of the class for both June and September exam sessions.

Computer Architecture II 5 Projects The projects are compulsory for passing the class. The projects will be posted on time in the webpage of the lecture. The projects will be done in groups of four students. At the end of the semester the projects will be presented by the team in a computer lab. The passing grade for each project is 5. The project grades will not be kept for a lecture in a future semester. For the September session the projects will be the same as the ones for the June session.
