Method and apparatus of processing floating point number

An apparatus of processing a plurality of first floating point numbers each having a mantissa and an exponent, comprising:

• a normalization circuit, for normalizing exponents of the first floating point numbers according to a minimum value of the exponents to generate normalized exponents of the first floating point numbers;
• a floating point number generation circuit coupled to the normalization circuit, for generating a plurality of second floating point numbers respectively corresponding to the first floating point numbers according to mantissas and the normalized exponents of the first floating point numbers;
• a processor coupled to a floating point number generation circuit, for perform a specific computation on the second floating point numbers to generate a plurality of third floating point numbers;
• and
• a de-normalization circuit coupled to the processor, for de-normalizing each of the normalized exponents to accordingly generate a de-normalization result and adjusting the third floating point numbers according to the de-normalization result.
