Dialogue: 0,0:00:10.67,0:00:13.84,*Default,NTP,0000,0000,0000,,Hi,can you tell us your names and department of what courses will be discussing today?
Dialogue: 0,0:00:14.16,0:00:19.48,*Default,NTP,0000,0000,0000,,I'm Anantha Chandrakasan from the EECS department and the course is 6.111.
Dialogue: 0,0:00:20.67,0:00:23.02,*Default,NTP,0000,0000,0000,,I'm Donald Troxel from EECS department.
Dialogue: 0,0:00:23.69,0:00:28.76,*Default,NTP,0000,0000,0000,,The 6.111 for people outside MIT who deal with names of courses
Dialogue: 0,0:00:28.93,0:00:32.18,*Default,NTP,0000,0000,0000,,is Introductory Digital Project Laboratory.
Dialogue: 0,0:00:32.50,0:00:35.43,*Default,NTP,0000,0000,0000,,Can you tell me what happens on a day-to-day base in the class?
Dialogue: 0,0:00:36.77,0:00:42.06,*Default,NTP,0000,0000,0000,,So basically 6.111 is a introductory digital logic design class
Dialogue: 0,0:00:42.25,0:00:50.18,*Default,NTP,0000,0000,0000,,where we are emphasyzing the basics of logic design and is very lab-focused class.
Dialogue: 0,0:00:51.04,0:00:54.47,*Default,NTP,0000,0000,0000,,The students spend a significant amount of time in the lab
Dialogue: 0,0:00:55.07,0:01:00.16,*Default,NTP,0000,0000,0000,,constructing and debuging digital designs on lab kits.
Dialogue: 0,0:01:00.52,0:01:03.59,*Default,NTP,0000,0000,0000,,So what kind of lab projects do the students do with the lab kits?
Dialogue: 0,0:01:04.80,0:01:09.57,*Default,NTP,0000,0000,0000,,There's a wide range of projects and they are implementing their projects primarily on
Dialogue: 0,0:01:09.81,0:01:12.57,*Default,NTP,0000,0000,0000,,Field Programmable Gate Arrays,
Dialogue: 0,0:01:12.90,0:01:15.93,*Default,NTP,0000,0000,0000,,and we have a couple of different versions of the lab kit around.
Dialogue: 0,0:01:16.44,0:01:22.55,*Default,NTP,0000,0000,0000,,Typically they end up doing projects related to video or audio processing
Dialogue: 0,0:01:23.17,0:01:31.11,*Default,NTP,0000,0000,0000,,and more recently there are also introduced wireless technology into 6.111 so they are dealing with the wireless.
Dialogue: 0,0:01:31.54,0:01:37.94,*Default,NTP,0000,0000,0000,,They also do a number of projects with motors and things that move as well.
Dialogue: 0,0:01:38.96,0:01:43.29,*Default,NTP,0000,0000,0000,,We encourage them to do something other than simply blink lights.[ Blink Lights is a very simple and fundamental design at introductory level ]
Dialogue: 0,0:01:44.30,0:01:47.67,*Default,NTP,0000,0000,0000,,And do the students do most of the work individually or in teams or..?
Dialogue: 0,0:01:47.85,0:01:53.33,*Default,NTP,0000,0000,0000,,Ah these projects are typically done in teams.Usually the group size is two or three.
Dialogue: 0,0:01:55.23,0:01:56.94,*Default,NTP,0000,0000,0000,,Okay.And how is their class changed over the years?
Dialogue: 0,0:01:57.13,0:01:58.83,*Default,NTP,0000,0000,0000,,I mean students have been taught at MIT for a long time.
Dialogue: 0,0:01:59.68,0:02:03.35,*Default,NTP,0000,0000,0000,,So I can speak to the current state of the course.
Dialogue: 0,0:02:03.46,0:02:07.44,*Default,NTP,0000,0000,0000,,Maybe Don could address some of the history of 6.111.
Dialogue: 0,0:02:07.63,0:02:12.78,*Default,NTP,0000,0000,0000,,Currently we are focused on implementation in Field Programmable Gate Arrays
Dialogue: 0,0:02:12.92,0:02:17.05,*Default,NTP,0000,0000,0000,,using hardware description languages,
Dialogue: 0,0:02:17.19,0:02:24.09,*Default,NTP,0000,0000,0000,,so we use the Verilog programming language to map a high level design into a hardware platform,
Dialogue: 0,0:02:25.07,0:02:32.42,*Default,NTP,0000,0000,0000,,and the designs are typically in the FPGA but they deal with a variety of interface circuits using
Dialogue: 0,0:02:32.61,0:02:36.18,*Default,NTP,0000,0000,0000,,using analogue-digital converters and digital-analogue converters
Dialogue: 0,0:02:36.39,0:02:42.00,*Default,NTP,0000,0000,0000,,and they deal with a variety of IO devices such as cameras,displays,motors and so on.
Dialogue: 0,0:02:42.21,0:02:47.21,*Default,NTP,0000,0000,0000,,So our focuses are primarily implementation using FPGAs.
Dialogue: 0,0:02:47.74,0:02:49.36,*Default,NTP,0000,0000,0000,,Maybe Don could say a few words more..
Dialogue: 0,0:02:49.46,0:02:54.28,*Default,NTP,0000,0000,0000,,Well in the begining we didn't have any FPGAs or any programmable devices,
Dialogue: 0,0:02:54.72,0:02:59.38,*Default,NTP,0000,0000,0000,,but we always had projects that students design.
Dialogue: 0,0:02:59.60,0:03:03.32,*Default,NTP,0000,0000,0000,,So something has changed,the technology is changed,
Dialogue: 0,0:03:03.41,0:03:08.95,*Default,NTP,0000,0000,0000,,the ability to design complex systems and simulation and design them
Dialogue: 0,0:03:09.08,0:03:14.17,*Default,NTP,0000,0000,0000,,with hardware description languages has come about and we can do very complicated things.
Dialogue: 0,0:03:14.42,0:03:22.88,*Default,NTP,0000,0000,0000,,But the thing hasn't changed is that the projects are of a design that the students make
Dialogue: 0,0:03:23.06,0:03:27.44,*Default,NTP,0000,0000,0000,,and they actually implement it and of course somethings don't work at first,
Dialogue: 0,0:03:28.49,0:03:32.66,*Default,NTP,0000,0000,0000,,and so they figure out how things don't work and what's wrong with them and fix them.
Dialogue: 0,0:03:32.93,0:03:42.54,*Default,NTP,0000,0000,0000,,So the impetus of the projects that staying the same has been that we actually make things work.
Dialogue: 0,0:03:43.47,0:03:46.79,*Default,NTP,0000,0000,0000,,So today we're picking a little bit of some of the student final projects.
Dialogue: 0,0:03:46.96,0:03:50.33,*Default,NTP,0000,0000,0000,,Can you describe the amount of work the students have done to finish these projects?
Dialogue: 0,0:03:50.58,0:03:56.77,*Default,NTP,0000,0000,0000,,So the fair of little work,there is,ah,over a  period of one month,
Dialogue: 0,0:03:56.92,0:03:59.82,*Default,NTP,0000,0000,0000,,the students are..,actually the projects are open
Dialogue: 0,0:03:59.95,0:04:03.32,*Default,NTP,0000,0000,0000,,and so the students get to define each group gets to define the project,
Dialogue: 0,0:04:03.90,0:04:07.87,*Default,NTP,0000,0000,0000,,specify the design,go to the detailed implementation,
Dialogue: 0,0:04:08.02,0:04:12.04,*Default,NTP,0000,0000,0000,,process the testing process and debuging process and so on.
Dialogue: 0,0:04:12.13,0:04:20.31,*Default,NTP,0000,0000,0000,,So it's a fairly involved process,and they do a seiries of design reviews with the course staff.
Dialogue: 0,0:04:20.94,0:04:29.62,*Default,NTP,0000,0000,0000,,So it's about a month worth of work and of course the last few days are particularly busy
Dialogue: 0,0:04:29.71,0:04:31.73,*Default,NTP,0000,0000,0000,,trying to get the designs working.
Dialogue: 0,0:04:32.37,0:04:35.50,*Default,NTP,0000,0000,0000,,And how do you feel abot how the projects have turned out this year?
Dialogue: 0,0:04:36.37,0:04:46.30,*Default,NTP,0000,0000,0000,,Ah the projects are really great and it was great to see all of the work all starting with a specification,
Dialogue: 0,0:04:46.92,0:04:52.98,*Default,NTP,0000,0000,0000,,we can see the end product everything from video games to multimedia processing and wireless and so on.
Dialogue: 0,0:04:53.10,0:04:55.65,*Default,NTP,0000,0000,0000,,So we are able to see a wide spectrum of projects survey.
Dialogue: 0,0:04:56.03,0:04:57.00,*Default,NTP,0000,0000,0000,,Okay and the ...
Dialogue: 0,0:04:57.19,0:05:00.40,*Default,NTP,0000,0000,0000,,Well the students would agree with me or not,
Dialogue: 0,0:05:00.60,0:05:04.89,*Default,NTP,0000,0000,0000,,actually I think they would that the result of getting a project to work,
Dialogue: 0,0:05:09.58,0:05:13.15,*Default,NTP,0000,0000,0000,,they had a experience of getting someting really complicated,
Dialogue: 0,0:05:13.42,0:05:12.17,*Default,NTP,0000,0000,0000,,they didn't really know whether they could do,to work.
Dialogue: 0,0:05:13.93,0:05:19.54,*Default,NTP,0000,0000,0000,,And their confidence and tackling future projects and future tasks
Dialogue: 0,0:05:20.39,0:05:26.46,*Default,NTP,0000,0000,0000,,would be in their basis work here in MIT or elsewhere  or in product design company.
Dialogue: 0,0:05:27.43,0:05:33.10,*Default,NTP,0000,0000,0000,,Their confidence is greatly enhanced by having a success getting their projects to work.
Dialogue: 0,0:05:33.52,0:05:40.83,*Default,NTP,0000,0000,0000,,And I think to add to that I would say that sort of working in a team sort of tackling a large system
Dialogue: 0,0:05:40.97,0:05:44.14,*Default,NTP,0000,0000,0000,,and partitioning the design into smaller blocks
Dialogue: 0,0:05:44.28,0:05:46.53,*Default,NTP,0000,0000,0000,,and getting smaller blocks to work together in a larger system
Dialogue: 0,0:05:46.74,0:05:52.73,*Default,NTP,0000,0000,0000,,is a very valuable experience and that's something that this course really emphasizes.
Dialogue: 0,0:05:53.04,0:05:56.70,*Default,NTP,0000,0000,0000,,I would like to make one comment about the ammount time that people spent.
Dialogue: 0,0:05:57.42,0:06:02.24,*Default,NTP,0000,0000,0000,,As Anantha said that it is concentrated in the last weeks or so,
Dialogue: 0,0:06:02.42,0:06:03.93,*Default,NTP,0000,0000,0000,,two weeks of the course.
Dialogue: 0,0:06:04.16,0:06:09.31,*Default,NTP,0000,0000,0000,,But around MIT we rate things in terms of units,
Dialogue: 0,0:06:09.59,0:06:13.70,*Default,NTP,0000,0000,0000,,meaningly amount of time that they would spend on average per week.
Dialogue: 0,0:06:14.20,0:06:21.59,*Default,NTP,0000,0000,0000,,And the students over the years have pretty consistently said that they spend
Dialogue: 0,0:06:21.89,0:06:27.62,*Default,NTP,0000,0000,0000,,about 18 to 20 hours per week average throughout the term for 6.111,
Dialogue: 0,0:06:28.02,0:06:31.84,*Default,NTP,0000,0000,0000,,and so we have a way..we were unsuccessful of having a way
Dialogue: 0,0:06:31.98,0:06:36.10,*Default,NTP,0000,0000,0000,,of having people learn how to do things with a smaller amount of time,
Dialogue: 0,0:06:36.30,0:06:38.67,*Default,NTP,0000,0000,0000,,but we do have a way of adding extra units
Dialogue: 0,0:06:38.94,0:06:45.88,*Default,NTP,0000,0000,0000,,so that we can have 18 units worth of credit for people which is,
Dialogue: 0,0:06:46.14,0:06:49.64,*Default,NTP,0000,0000,0000,,I think more or less fair although it is concentrated in the last few weeks.
Dialogue: 0,0:06:49.93,0:06:50.69,*Default,NTP,0000,0000,0000,,That's the nature.
Dialogue: 0,0:06:50.81,0:06:56.27,*Default,NTP,0000,0000,0000,,Okay well thanks for your time today and thank you also for sharing your materials with MIT open course ware.
Dialogue: 0,0:06:56.75,0:06:57.52,*Default,NTP,0000,0000,0000,,Thank you very much.
