Multipurpose memory system for use in a graphics system
First Claim
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.

Abstract
A graphics system may include a frame buffer, a processing device coupled to output data, a multipurpose memory device that includes a plurality of storage locations and is coupled to store data output from the processing device, and a multipurpose memory controller coupled to the multipurpose memory device. The multipurpose memory controller may be configured to allocate a first plurality of the storage locations to a first image buffer configured to store image data, a second plurality of the storage locations to a first texture buffer configured to store texture data, and a third plurality of the storage locations to a first accumulation buffer configured to store accumulation buffer data. The multipurpose memory device may be configured to include a first image buffer, a first texture buffer, and a first accumulation buffer at the same time.
