2-Stage float32 Multiplier

The module multiplies two 32-bit float32 values. To keep the exercise focused, the test covers finite normalized values and zero.

Behaviour

• i_valid='1' presents a new operand pair;
• the matching output appears exactly 2 cycles later with o_valid='1';
• stage 1: extract sign, exponents, mantissas and multiply 24x24 mantissas;
• stage 2: normalize, adjust exponent and rebuild the float32;
• i_reset='1' clears o_valid and o_y.
