Graphic processing unit and method for decompressing data

摘要

A graphic processing unit (GPU) and method for decompressing compressed 3-dimensional (3D) compressed data. The GPU may extract segment information by analyzing a compressed data header and decompress segments included in a bit stream based on the segment information.

1. A graphic processing unit (GPU) to decompress compressed 3-dimensional (3D) object data in association with a central processing unit (CPU), the GPU comprising:
a segment information extractor to extract segment information included in a compressed data header, by analyzing the compressed data header included in a bit stream of compressed data received from the CPU; and a decompressor to
decompress segments of the compressed 3D object data included in the bit stream based on the segment information, the compressed 3D object data being 3D object data divided into the segments and compressed, andstore vertex position information and vertex connection information, which are a result of decompression, in a memory according to address information included in a segment header of each of the segments, wherein the segment header of at least one of the segments comprises a write address information, and wherein the write address information comprises address information indicating a start of the storing, in a second memory space, the vertex position information and the vertex connection information.
