Biased Exponents Help

[lRhyss]

Okay, I've Googled this and I really can't find the answer, just explanations. Therefore I hope someone can help me here D:

Okay, I have the Binary representation of an exponent and the bias is 2^3 = 8

So if the Binary representation was 0000 would the biased form be 0?

And if it was 0001 would it be 1 or -1?

And if it was 0010 would it be 2 or -2?

Just a little confused haha :')

Your bias is 8 so you add 8 to every exponent to get the biased exponent.
0 becomes 8 (0000 -> 1000)
1 becomes 9 (0001 -> 1001)
-1 becomes 7 (-0001 -> 0111)

It's basically an alternative to 2's complement that has trade-offs which are useful for floating point numbers.

That's my fill of feeling stupid for the night filled.

You never stop getting filled... with stupid.

Hey I'm only learning this stuff I don't really understand it :/

I wasn't calling you stupid, I meant I felt stupid!!

Oh I am very sorry D: I'm only coming to grips with sarcasm over the internet and I seem to have really miss-read your post D:

Also one more thing:

I have a question about RTL, I wanna know if I have this right :P (Lost my notes)

would X = Y + Z

Be:

M(X) = [M(Y)] + [M(Z)] in RTL?

It's nicer to have someone answer your questions rather than Google, sorry :P

Assuming in this context that RTL means register transfer level then I'm going to need more information. Is this VHDL?

I have no clue, the question on my revision sheet just literally says

" If the C++ was X = Y + Z

Write the RTL translation"


and yeah it's register transfer language :P

it's register transfer language :P

Which one?
