Abstract
The present invention includes a processor, a storage device having compressed texture data, a texture buffer having decompressed texture data. The processor reads the compressed texture data from the storage device and decompresses the texture data. The processor then stores the decompressed texture data in the texture buffer.
Claims26
An apparatus for image processing, comprising:
- a processor including a data decompression circuit;
- a first storage device having texture data and electronically coupled to said processor;
- and
- a texture buffer having decompressed texture data and being directly connected to said processor;
- wherein
- transmission of texture data between said texture buffer and said processor is faster than transmission of texture data between said storage device and said processor;
- and
- said first storage device is defined by a CPU work memory or an external memory device.

An apparatus for image processing, comprising:
- a processor including a data decompression circuit;
- a first storage device having texture data and electronically coupled to said processor;
- a texture buffer having decompressed texture data and being directly connected to said processor;
- and
- a first data bus and a second data bus, wherein said first data bus carries texture data between said texture buffer and said processor faster than said second data bus carries texture data from said storage device and said processor;
- and

4 more elements
An image processing method comprising the steps of:
- providing compressed texture data in a storage device defined by a CPU work memory or an external memory device;
- reading said compressed texture data from said storage device and decompressing said compressed texture data;
- storing said decompressed texture data in a texture buffer;
- and
- directly connecting a processor to said texture buffer, and transferring data between said texture buffer and said processor faster than transferring data between said storage device and said processor.
