Abstract:
A graphics processor for receiving parameters defining a polygon from a host processor, interpolating said parameters defining a polygon to map said polygon to a pixel grid, and rendering said polygon in successive orthogonal scan lines to be displayed on said pixel grid, said graphics processor comprising:a host interface for receiving said parameters defining a polygon from said host processor;a register file coupled to said host interface and capable of storing said parameters defining a polygon; anda polygon engine coupled to said register file for mapping said parameters defining a polygon to said pixel grid, said polygon engine comprising:an error correction circuit coupled to said register file for calculating corrected parameters to prevent interpolation errors and for storing said corrected parameters into said register file; andan interpolation circuit coupled to said register file for interpolating said corrected parameters to map said polygon to said pixel grid,wherein said error correction circuit replaces a first parameter in said register file with a first corrected parameter.
