Abstract | A processor may have at least one multiplier unit which can be controlled to operate in a signed, an unsigned, or a mixed sign mode; a multiplier unit mode decoder coupled with the multiplier unit which receives location information of a first and second operands, wherein the multiplier mode decoder controls the multiplier unit when in the mixed sign mode depending on the location information to operate in a signed mode, an unsigned mode, or a combined signed/unsigned mode.
L'invention porte sur un processeur qui peut avoir au moins une unité de multiplicateur qui peut être commandée pour fonctionner dans un mode signé, non signé ou à signe mixte ; un décodeur de mode d'unité de multiplicateur couplé à l'unité de multiplicateur qui reçoit des informations de localisation de premier et second opérandes, le décodeur de mode de multiplicateur commandant l'unité de multiplicateur dans le mode à signe mixte en fonction des informations de localisation pour fonctionner dans un mode signé, un mode non signé ou un mode signé/non signé combiné. |
