----------------------------------- btiffin Wed May 28, 2008 2:00 pm Half-adders full-adders and electronics ----------------------------------- So, how many compsci.ca members know about the logic and electronics of computing? Did you know that a half-adder (take 2 bits and returns a sum and a carry) is the simple application of an xor for the sum and an and for the carry? Or that a full-adder (take 2 bits plus a carry and return a sum and a carry) is the equivalent of oring two half-adders? Or that a string of full-adder circuits can add up any number of bits; usually in 8, 16, 32 or 64 (or more) bit chunks? Or how this boolean thinking can go from whoa? to whoa! in its ability to perform complex tasks? :) Just curious, Cheers ----------------------------------- apomb Wed May 28, 2008 3:19 pm RE:Half-adders full-adders and electronics ----------------------------------- Yep... thats much like the stuff I did in my digital electronics course this past year. only we didnt use adders and half adders, we used different flipflops to do adding, counting and boolean hubub. I found it extremely enjoyable. ----------------------------------- tenniscrazy Wed May 28, 2008 8:49 pm RE:Half-adders full-adders and electronics ----------------------------------- yes! i did this stuff last semester in computer engineering. It was pretty fun making all the circuits. Its like finally finding out HOW a computer essentially works at the simplest level. And also gives some meaning to machine coding and how hard and much longer it was ----------------------------------- apomb Wed May 28, 2008 8:55 pm RE:Half-adders full-adders and electronics ----------------------------------- what grade comp eng.? ----------------------------------- tenniscrazy Wed May 28, 2008 9:00 pm RE:Half-adders full-adders and electronics ----------------------------------- grade 11. they just added in grade 10 engineering for this year or i would've taken it last year ----------------------------------- apomb Wed May 28, 2008 9:05 pm RE:Half-adders full-adders and electronics ----------------------------------- its an interesting feild, especially if you're more of a hands-on learner, but also like to be academic. What are you planning for post-secondary? ----------------------------------- tenniscrazy Wed May 28, 2008 9:08 pm RE:Half-adders full-adders and electronics ----------------------------------- i'm planning on focusing on math, because that is what everything that i'm interested in is based on in the most basic level. Also i got a taste of university math theory when i visited Guelph, and i REALLY enjoyed it. But i could branch out into computer science or computer engineering. ----------------------------------- rizzix Wed May 28, 2008 9:44 pm RE:Half-adders full-adders and electronics ----------------------------------- Had to do it. It's part of the curriculum. ----------------------------------- rdrake Wed May 28, 2008 10:12 pm RE:Half-adders full-adders and electronics ----------------------------------- I too did it in school. Computer Architecture I, interesting course. ----------------------------------- Skynet Wed May 28, 2008 10:41 pm Re: Half-adders full-adders and electronics ----------------------------------- Yep, but I have a less CS-y background than most. ----------------------------------- jernst Thu May 29, 2008 6:54 am Re: Half-adders full-adders and electronics ----------------------------------- I wish I would have taken more if it in high school when I was there, instead I stuck with mostly programming type courses so when I finally got a chance to do that type of stuff in Uni I found it a little tricky :P ----------------------------------- Bobrobyn Fri May 30, 2008 12:40 pm RE:Half-adders full-adders and electronics ----------------------------------- Yeah, I did this stuff in highschool, and a course (I can't remember the title) in university -- the same course we learned assembly in. ----------------------------------- Epic Tissue Fri Jun 06, 2008 9:36 am RE:Half-adders full-adders and electronics ----------------------------------- Had a course in this too. ----------------------------------- apomb Fri Jun 06, 2008 10:04 am Re: RE:Half-adders full-adders and electronics ----------------------------------- Had a course in this too. Thanks for that riveting commentary... If anyone is interested in electronics/ microcontrollers, check out [url=http://www.instructables.com/id/How-to-choose-a-MicroController/] this instructable for choosing an appropriate one for your project. I'm very interested in a Motorola one, since i already know the command set. ----------------------------------- Epic Tissue Fri Jun 06, 2008 10:29 am Re: RE:Half-adders full-adders and electronics ----------------------------------- Had a course in this too. Thanks for that riveting commentary... What? ----------------------------------- apomb Fri Jun 06, 2008 12:13 pm RE:Half-adders full-adders and electronics ----------------------------------- sarcasm is one of my many interests, along with electronics.
