Question

Please identify and elaborate briefly regarding your recommended register-level components needed to realize the normalization block in an IEEE-754 Floating-Point Multiplier circuit. For full credit, your response must consist of at least 5 complete sentences, but not have more than 7 sentences.

One or vro → * Nocnalization i The nosumalization stage in a seadis- 2 based floating -point multiplier is trivial if rrectly as long as subnormal numbere support is not required Depending whether the MSB of the result is a (to 1) multiplexer shifts the mantissa at most one step. However, the nomalizer must be able to shift the entire width of the result, if subnormal numbers are supported at the inputs of multiplier Due to this normalization wit of floating point multipléese is more costly than the nomuslication unit of Addon A better option is to add support for neanaliza tion of one of the inputs to the multipliese beforce any multiplication is perfecundo [It is not necessary to nogumalize betth numbers before multiplication as the product of two subnormal numbers will be zero] In HR FPgg format, IEEE - 754 tlf. style subnormal numbers are instead emulated by using an extended exponent gange.
