Abstract: A method to classify source data in a processor in response to a vector floating-point classification instruction includes specifying, in respective fields of the vector floating-point classification instruction, a source register containing the source data and a destination register to store classification indications for the source data. The source register includes a plurality of lanes that each contains a floating-point value and the destination register includes a plurality of lanes corresponding to the lanes of the source register. The method further includes executing the vector floating-point classification instruction by, for each lane in the source register, classifying the floating-point value in the lane to identify a type of the floating-point value, and storing a value indicative of the identified type in the corresponding lane of the destination register.
