Abstract
Implementations of transforms, such as a discrete cosine transform (DCT) and inverse DCT on a graphics processing unit (GPU), use direct matrix multiplication. GPU features such as parallel graphics pipelines, multi-channel capability, and multiple render targets are used to obtain significantly faster processing speeds than on a conventional central processing unit (CPU). Various rendering modes may be used, such as point rendering mode, line rendering mode, and triangle or quadrilateral rendering mode.
