Abstract:
A graphics processing unit comprising:a processor for outputting graphic data including a floating-point data string which represents information for specifying a graphic to be drawn in the floating point format;a rendering unit for expanding and outputting a graphic to pixels according to drawing data including a fixed-point data string which represents the content of a graphic to be drawn in the fixed-point format, anda data converter for converting floating-point data included in said graphic data output by said processor to fixed-point data and outputting it to said rendering unit as said drawing data,said data converter having decimal point position changing means for changing the bit position of decimal point of fixed-point data to which floating-point data is to be converted,said processor outputting scale factor data for designating the bit position of a decimal point of fixed-point data to which each floating-point data is to be converted as said graphic data together with said floating-point data string, andthe decimal point changing means of said data converter allowing the bit position of fixed-point data to which said each floating-point data is to be converted to set to the bit position of a decimal point designated by said scale factor data included in said graphic data output by said processor for said floating-point data.
