Description (PRELIMINARY)

GDD400 Digital Image/Video Processing and Graphics Library
for TMS320C6000.

GDD400 is a set of Digital Image/Video Processing and
Graphics primitives functions optimized algorithmically and
on the assembly level for TMS320C6000 VLIW architecture.

The library provides with a wide range of still image operations
such as arithmetic, logical and bitwise operations, image
formats conversions, 2D and 3D transforms, filtering and
histograms, video stream manipulation.

Library functions are operating system independent and
can be used in any run-time environment with TI Code Generation
Tools.

Target applications: medical and industrial image processing,
video editing, control and automation, robotics, surveillance,
machine vision, spectral analysis, image analysis, military,
target guidance identification and control, TV, test and measurement,
diagnostic, telecomm.

Target hardware: TMS320C62xx, TMS320C64xx, TMS320DM64xx,
TMS320C67xx DSPs.

The library would include following sections/operations
(the list of functions is not complete and will be defined
and described in more details soon)
