Abstract:
A method for displaying computer graphics data, comprising the steps of:(a) selecting a first compression technique; (b) selecting a second compression technique; (c) compressing a current row of pixels using both said first and second compression techniques producing a first compressed row data and a second compressed row data; (d) selecting either said first compressed row data or said second compressed row data based on a size of said first and second compressed row data; (e) storing said selected compressed row data for a previous row of pixels in a portion of frame buffer memory; (f) reserving a portion of frame buffer memory; (g) dividing said computer graphics data into blocks of pixels; (h) selecting a current block of pixels for processing; (i) initializing a row counter to represent a bottom row of pixels within said current block of pixels; (j) creating a status data for said current row of pixels for said selected compressed row data; (k) storing said status data for said previous row of pixels in said portion of frame buffer memory; and (l) decrementing said row counter.
