Issue 106: Add a driver for the Image Processing Unit
Reported by Paul Cercueil, Aug 28, 2012
The IPU is a built-in peripheral dedicated to image processing. It permits to scale and convert an image using the YUV pixel format (and RGB on newer SoCs) to RGB, from memory to memory, or to the LCD. Having a driver for that hardware in the kernel would allow us to offload the scaling/conversion done by video players like MPlayer to the hardware. The work could start by looking at dvdk's build of MPlayer, which makes use of the IPU from user-space using /dev/mem. The driver should provide a v4l2 API.

Add more information for process imaging unit, I am very happy and getting the great objectives as well. Keep follow https://www.resumewriterslist.com/novoresume-com-review/ and get the interesting resume reviews and more methods with us.
