Abstract: A method includes receiving, by a frame converter, a frame of pixel data and converting, by the frame converter, the frame to a first frame division unit. The method also includes receiving, by a translation circuit, a pixel coordinate and cropping and shifting, by the translation circuit, the first frame division unit based on the pixel coordinate, to produce a second frame division unit. Additionally, the method includes outputting, by the translation circuit, the second frame division unit.

Abstract: A method includes converting a frame of pixel data to a first frame division unit. The method further includes, responsive to an X,Y coordinate, cropping and shifting the frame division unit to produce a second frame division unit. The method also includes outputting the second frame division unit.

Abstract: A system includes a display device configured to display frames of images, a memory coupled to the display device and configured to store image data representing a sequence of the frames, and a memory controller coupled to the memory. The memory controller is configured to split a frame in the sequence of frames into a slice count of frame slices according to an order of respective frame slice numbers, partition the memory into a number of buffer slices in an ordered sequence wherein the number of buffer slices is greater than or equal to the slice count, write each frame slice in the sequence of frames to a next free buffer slice in the ordered sequence of buffer slices, read each written frame slice to the display device to display the written frame slice with other displayed frame slices according to the order of the respective frame slice numbers, and return to a first buffer slice in the ordered sequence after writing a frame slice in a last buffer slice in the ordered sequence.
