Memory interleaving technique for texture mapping in a graphics system

A method for storing a texture map in a plurality of memory devices, wherein the texture map comprises a plurality of texels, the method comprising:

• storing at least portions of the plurality of texels in respective ones of the plurality of memory devices;
• wherein an N×M array of texels corresponds to each pixel;
• wherein the texels are interleaved in the plurality of memories to allow, for each of the plurality of pixels, the plurality of memories to output a respective N×M array of texels for a pixel in parallel in a single read transaction.

A method for storing a texture map in a plurality of memory devices, wherein the texture map comprises a plurality of texels, wherein an N×M array of texels corresponds to each pixel, the method comprising:

• storing at least portions of the plurality of texels in respective ones of the plurality of memory devices, wherein said storing comprises storing texels in separate ones of the memory devices in an interleaved fashion;
• wherein, for each of the plurality of pixels, the plurality of memory devices are operable to output a respective N×M array of texels for at least two respective neighboring pixels in parallel in a single read transaction.

A method for storing a 3-D texture map in a plurality of memory devices, wherein the texture map comprises a plurality of texels, wherein an N×M×O array of texels corresponds to each pixel, the method comprising:

• storing at least portions of the plurality of texels in respective ones of the plurality of memory devices, wherein said storing comprises storing texels in separate ones of the memory devices in an interleaved fashion;
• wherein, for each of the plurality of pixels, the plurality of memory devices are operable to output a respective N×M×O array of texels for a respective pixel in parallel in a single read transaction.

A method for accessing a texture map from a plurality of memory devices, wherein the texture map comprises a plurality of texels, wherein an N×M array of texels corresponds to each pixel, the method comprising:

• storing at least portions of the plurality of texels in respective ones of the plurality of memory devices, wherein said storing comprises storing texels in separate ones of the memory devices in an interleaved fashion;
• generating a read transaction for an N×M array of texels for a respective pixel;
• the plurality of memory devices outputting the N×M array of texels for the respective pixel in parallel in a single cycle in response to the read transaction.

A graphics system, comprising:

• a plurality of memory devices for storing a texture map, wherein the texture map comprises a plurality of texels, wherein an N×M array of texels corresponds to each pixel,
• wherein the plurality of memory devices store at least portions of the plurality of texels, wherein the plurality of memory devices store texels in separate ones of the memory devices in an interleaved fashion;
• wherein, for each of the plurality of pixels, the plurality of memory devices are operable to output a respective N×M array of texels for a respective pixel in parallel in a single read transaction.
