System and method for DMA controlled image processing

A system for processing image data from a plurality of images, the system comprising:

• a register, the register providing descriptors as to locations of the plurality of images;
• a DMA fetching module, the DMA fetching module being coupled to the register, the DMA fetching module being configured to fetch the image data from the plurality of images, the DMA fetching module including a DMA master and a plurality of DMA channels, the plurality of DMA channels fetching image tiles of pixel data in a certain fetching order, each of the plurality of DMA channels fetching at least one of the image tiles from at least one of the plurality of images, the DMA master controlling the fetching;
• and
• a display blender, the display blender blending the plurality of images into a single combined image to be displayed,
• wherein the image tiles are generated from the at least one of the plurality images when the plurality of DMA channels perform the fetching, and
• wherein the plurality of image sources generate a plurality of the image data to be fetched, that are of different resolution, orientation, and/or color space.

A method for processing image data from a plurality of images, the method comprising:

• transferring each of a plurality of images to one of a plurality of DMA channels;
• fetching a plurality of image tiles of pixel data in a certain fetching order by utilizing each of the plurality of DMA channels to fetch the plurality of image tiles from at least one of the plurality of images, wherein the plurality of image tiles are generated from the at least one of the plurality images when the plurality of DMA channels perform the fetching;
• and
• blending the fetched plurality of image tiles to generate a combined image,
• wherein the plurality of images are of different resolution, orientation, and/or color space.

A method for processing image data from a plurality of images, the method comprising:

• storing at least one image source data in a memory;
• configuring a plurality of descriptors as to a location of the at least one image source data and an output image format for the at least one image source data;
• reading a link list stored in the memory utilizing a DMA master, the link list including the plurality of descriptors;
• reading a tile of the at least one image source data based on the plurality of descriptors, the tile of the at least one image source data being a portion of the at least one image source data;
• fetching the tile of the at least one image source data in a certain fetching order by utilizing a plurality of DMA channels;
• image processing the stored tile of the at least one image source data;
• and
• displaying the image processed tile of the at least one image source data,
• wherein the tile is generated from the at least one image source data when the reading and the fetching are performed, and
• wherein the at least one image source data is of different resolution, orientation, and/or color space from another source data.
