Abstract
A device configured to display images. The device comprises a storage component, a first buffer, a second buffer and a display controller. The first buffer comprises a plurality of memory locations and is configured to store a first image from the storage component. The second buffer comprises a plurality of memory locations and is configured to store a second image from the storage component. The memory locations of the first buffer are interleaved with the memory locations of the second buffer in a common memory space. The display controller is coupled to the first and second buffers and is configured to retrieve a part of the first image from the first buffer and a part of the second image from the second buffer.

A device configured to display images, the device comprising:
- a storage component configured to store a plurality of images;
- a first buffer comprising a plurality of memory locations, the memory locations configured to store a first image from the storage component;
- a second buffer comprising a plurality of memory locations, the memory locations configured to store a second image from the storage component, wherein the memory locations of the first buffer are interleaved with the memory locations of the second buffer in a common memory space;
- and
- a display controller coupled to the first and second buffers, the display controller configured to retrieve a part of the first image from the first buffer and a part of the second image from the second buffer, the display controller further configured to send the retrieved image parts to a display.
A method of displaying images, the method comprising:
- copying a first image from a storage component into a first buffer and copying a second image from the storage component into a second buffer, the first and second buffers comprising a plurality of memory locations interleaved in a common memory space;
- retrieving a part of the first image from the first buffer and a part of the second image from the second buffer;
- and
- sending the retrieved parts to a display.
