Examples
34.3 Examples
This section includes several examples of programming the PXP to render an output image.
The image could be either a still image or one frame of a sequence of video images. For
each case, the input and output images will be shown along with a table of PXP register
settings. In all examples, pointers to the data structures with image data will be referred to
in the following notation: *imagename_type, where imagename indicates which image is
being used and type indicates either luma (y), chroma (u, v) or RGB data (rgb). All register
names are assumed to have the HW_PXP_ register prefix. The registers can be written in
any order except the HW_PXP_CTRL register, which must be written last since it enables
the PXP's operation.
34.3.1 Basic QVGA Example
This example shows how to perform basic color space conversion of a 3-plane YUV image
into an RGB image suitable for an LCD device.
