System and method for compressing bounding box data and processor incorporating the same

摘要

Methods of compressing (and decompressing) bounding box data and a processor incorporating one or more of the methods. In one embodiment, a method of compressing such data includes: (1) generating dimension-specific multiplicands and a floating-point shared scale multiplier from floating-point numbers representing extents of the bounding box and (2) substituting portions of floating-point numbers representing a reference point of the bounding box with the dimension-specific multiplicands to yield floating-point packed boundary box descriptors, the floating-point shared scale multiplier and the floating-point packed boundary box descriptors together constituting compressed bounding box data.

1. A method of compressing bounding box data, comprising:
generating, by a processor, dimension-specific multiplicands and a floating-point shared scale multiplier from floating-point numbers representing extents of said bounding box; and substituting, by said processor, portions of floating-point numbers representing a reference point of said bounding box with said dimension-specific multiplicands to yield floating-point packed boundary box descriptors, said floating-point shared scale multiplier and said floating-point packed boundary box descriptors together constituting compressed bounding box data.
