Abstract
An apparatus and method for performing a floating point multiply (by a fixed graphics constant), and converting the product of the multiply into an integer, within a single operation is provided. The apparatus includes detection logic to determine whether a special multiply/convert operation is specified, and if so, floating point conversion logic to adjust a bias constant prior to conversion of the floating point number to an integer. More specifically, if the multiply/convert operation specified relates to calculation of graphic points for display, execution of the multiply convert operation effectively multiplies a specified floating point number by a graphics constant, as part of subtracting the exponent bias.
