Hey dude, thanks for the great video, no doubt clearer than my professor. One thing I want to ask is that, at 10:58, when you were doing sign extension for the last row, why is it extended with 0, instead of 1? Is it because the multiplier is negative? If so, does that mean if the multiplier is not negative, we extend it with 1? ( assuming that row is not multiplying by 0)

[@falak6552]

Means a lot sir.... Finally i have understood the concept......

I liked your presentation, it was clear and it made me understand so much more what we discussed in lectures. One thing I didn't quite understand is that how you could just "drop" and ignore the 1's after the 8th bit in the first example? Thank you for this video!

[@sbdaule]

Because those one's are equivalent to signed bit extension

why we are going for sign bit extension

[@canyavuz3680]

What if you go from 4 bits to 8 bits so you have 11110110 and 11111001 how du you do that because in 4 bits the last number was negated but which number gets negated there.

[@niharikabehera1593]

can u help me to write its varilog code???

[@stephenpark2082]

There is a simpler method: 1. Treat the computational process as regular unsigned multiplication (if one of the numbers or both of them are negative, convert them back to unsigned numbers first, using 2's complement ) 2. Perform multiplication 3. If the product is what we are looking for, then it is done. If the product should be negative, but it is positive, the method is simple, perform 2's complement to convert your product to a signed number. done. You are prone to make less mistakes using this method. Cheers.

[@juliazhang3600]

why and how did you add the sign extension

[@KarthikVippala]

Hey Julia ,thanks for asking the question . Why sign extension ? Because if don't extended according to sign then we will not get the same value , -ve will turn into +ve and vice versa . How did you add sign extension? Just simple binary addition 1+1 = sum is 0 carry is 1. 1+1 = 2 decimal , binary 010 1+1+1 = 3 decimal , binary 011 So on...

No

[@utkarshkathuria2931]

what will you do if the output can only be stored in 4 bits and not 8 bits?

[@KarthikVippala]

Hey Utkarsh thanks for asking the question, in this case data will be lost and we need exact bits for result

[@utkarshkathuria2931]

You mean we can't get exact result with 4bits

[@utkarshkathuria2931]

But I have been asked to do so using fixed point numbers and also round off the result. I am confused how to proceed. Any help is appreciated 😊

[@KarthikVippala]

Can you provide the question 👍

[@utkarshkathuria2931]

I have two 8 bit signed 2s compliment numbers (3bit integer and 5bit fraction). Have to multiply them and store result in 8bit only. Also have to round off

[@Abbas-xd1mc]

If the question is in 8 bits? We double the sign extension to 16?

[@KarthikVippala]

Yes Abbas you are correct, we need to extend till 16 bit for answer rest you can ignore. Thanks for asking the question 👍
