Course Website http://mpsoc.unife.it/~arch-dig/ All the course material and lab exercises will be uploaded on this website 4
Course Schedule and Material In theory, our schedule would have been: TUESDAYS FROM 14 TO 16:30 CAN BE LECTURE OR LAB. EXERCISE WEDNESDAYS FROM 16:30 to 19 In practice: I will upload my recorded lectures on Google Classroom (course code glxrzcw) every Wednesday and Thursday morning at latest (i.e., recordings available from the day after). Videoconference for Questions and Answers: each TUESDAY at 3pm during a ConfCall via Hangout Meet. 5
Laboratory Here we need to be creative…. …I may provide you the instructions to carry out lab. assignments via the course website. You would then be supposed to carry out such assignments on your laptop or home PC. You should notify as soon as possible whether YOU DO NOT HAVE A LAPTOP OR PC AT HOME. Just send me an email if you fall into this case. If you have a laptop or home PC, do not send me any email. 6
Exam The course ends with an ORAL exam, consisting of three questions that span the entire program. Capability to establish links between topics is preferred over memorizing notions. During the first pass of the course material, ask youself: «what is the main point this slide makes? What is the key take-away?». Do not care about the details. During the second pass of the course material, try to capture the details. During the third pass of the material, try to test your level of understanding of both the key take-aways and the technical details. You will then be in a position to estimate your final mark! In order to get the mark registered, you need to get a «pass» in the lab. assignments. 7
Recommended books No single book covers all the course content. This is an advanced course with several lectures covering frontier aspects of SoC design for embedded systems. Taking notes during the playback of online lectures is the best way to learn effectively. However, on some specific topics I can recommend reference books. See next slide. 8
