Abstract:
1. A multiplier device for generating, starting from a first binary digital signal and a second binary digital signal representing respective floating-point real numbers encoded in sign, exponent, and mantissa, an output signal representing a product of said real numbers, the device comprising: a multiplication module for performing a multiplication on bits of said mantissas and supplying at output a set of addenda of partial products; and a processing block for processing said partial products, which yields a product that is the result of the multiplication of the mantissas, wherein said multiplication module comprises a submatrix corresponding to a first subset of predetermined dimensions of the set of the addenda of partial products corresponding to most significant parts of the partial products, and wherein said multiplication module is further configured for rounding based on a second subset of the set of addenda, said second subset being external to said first subset.
