AMD X2 3800+ processor has bottleneck in integer multiplier ?

by "Skybuck Flying" <BloodyShame@[EMAIL PROTECTED] > May 6, 2008 at 11:48 PM

Hello,

I noticed how one of my applications performed an insane ammount of 32 bit

multiplies, and at the same time the app was kinda slow.

Now that I am reading the AMD do***entation again it says something like:

Multiplier on AMD processor is attached to pipeline 0, and such.

So to me it looks like this AMD processor only has one multiplier ALU.

Which could mean if there are multiple muls in the pipeline those can't be

executed.

So my conclusion:

The AMD X2 3800+ processor has a multiplication bottleneck ?! Oooeeehhhh
?! 
;)

Bye,
  Skybuck.
