Abstract
A method for assisting in data calculation by using a display card: In the present method, input data stored in a system memory is transformed into texture data, which is then stored in a display memory of the display card. Then, a Graphic processing unit (GPU) of the display card is used for executing a texture calculation to the texture data, and a result of the texture calculation is stored in a display target of the display memory. Finally, the display target is outputted to the system memory as the output data. Accordingly, a part of calculation tasks of a central processing unit (CPU) can be given to the GPU of the display card when the CPU is in a high usage rate, so as to reduce a calculation burden of the CPU.
Claims11
A method for assisting in data calculation by using a display card, suitable for applying a display card to calculate input data of a system to obtain output data, wherein the display card comprises a first processing unit and a display memory, and the system comprises a second processing unit and a system memory, the method comprising:
- transforming the input data into texture data, and storing the texture data in the display memory;
- wherein the step of transforming the input data into the texture data, and storing it in the display memory comprises:
- transforming image data into first texture data, wherein the image data comprises pixel values of a plurality of pixels of an image;
- transforming positions of the pixels to be referred to in the image into second texture data during a texture calculation;
- and
- storing the first texture data and the second texture data in the display memory;
- executing a texture calculation of the texture data by using the first processing unit;
- storing a result of the texture calculation in a display target of the display memory;
- and
- outputting the display target to the system memory as the output data.
