Is floating point IEEE754 binary digit represented using special unit/circuit for arithmetic operation?
We know that two un/signed integers arithmetic operation using special circuit called full-adder to execute arithmetic operation in Arithmetic Logic Unit (ALU).
The full-adder I mean is classical ...

Why does Intel's Haswell chip allow floating point multiplication to be twice as fast as addition?
I was reading this very interesting question on Stack Overflow:
Is integer multiplication really done at the same speed as addition on a modern CPU?
One of the comments said:
"It's worth nothing ...

Are floating point numbers denormalised before the processor performs arithmetic operations on them? [closed]
Does the processor denormalise the numbers in IEEE 754 notation and normalise the result after storing or are the arithmetic operations performed on the numbers as they are?
I'm asking because in case ...

Can anyone tell me what other computers used this floating-point format?
I have discovered that the DEC PDP-10 used a floating-point format that differed from IEEE-754 in an interesting way.
IEEE-754 is like sign-magnitude representation. The only difference between a ...

Is analog signal arithmetic faster than digital one?
Would it be theoretically possible to speed up modern processors if one would use analog signal arithmetic (at the cost of accuracy and precision) instead of digital FPUs (CPU -> DAC -> analog FPU -> ...
