1. A graphics system comprising:

  • a frame buffer;

    a multipurpose memory;

    a memory controller configured to allocate a texture buffer for storing texture data in the multipurpose memory, to allocate an image buffer for storing image data in the multipurpose memory, to allocate an accumulation buffer for storing accumulation buffer data in the multipurpose memory, wherein the multipurpose memory is configured to have data stored in the image buffer, the texture buffer, and the accumulation buffer at the same time, and wherein at least two of the image buffer, the texture buffer and the accumulation buffer are accessed with different interleaving patterns; and

    a processing device coupled to the frame buffer and the multipurpose memory, wherein the processing device is configured to read texture data, image data, and accumulation buffer data from the texture buffer, image buffer, and accumulation buffer respectively, and to perform texturing operations, image processing operations, and accumulation operations using the texture data, image data, and accumulation buffer data respectively.
