Title:
PROGRAMMABLE FOUR-TAP TEXTURE FILTER
Document Type and Number:
WIPO Patent Application WO2004001965
Kind Code:
A1
Abstract:
A programmable filter is provided for filtering image or texture map data. A weighting RAM stores weighting data for filtering data in both x and y directions. Different weighting values may be programmed into weighting RAMs to provide different weighting functions and also enable or disable a number of taps within the filter. A weighting value of zero, for example, may disable a particular tap for the filter. In the preferred embodiment, a number of lines in the x direction may be simultaneously weighted and then weighted and combined in the y direction to produce a filtered value within one clock cycle.
