The i.MX35 multimedia processor supports many display types. The Image Processing Unit (IPU) handles the display devices. This module also controls graphic interfaces such as cameras and 2D graphics acceleration. All IPU sub-modules are connected using a private DMA interface (IDMA). The IDMA is used only for the IPU to transfer data between sub-modules and also between IPU and the external memory.
