/**
|
||||
* Performs a Y2R colorspace conversion.
|
||||
*
|
||||
* The Y2R hardware implements hardware-accelerated YUV to RGB colorspace conversions. It is most
|
||||
* commonly used for video playback or to display camera input to the screen.
|
||||
*
|
||||
* The conversion process is quite configurable, and can be divided in distinct steps. From
|
||||
* observation, it appears that the hardware buffers a single 8-pixel tall strip of image data
|
||||
* internally and converts it in one go before writing to the output and loading the next strip.
|
||||
*
|
||||
* The steps taken to convert one strip of image data are:
|
||||
*
|
||||
* - The hardware receives data via CDMA (http://3dbrew.org/wiki/Corelink_DMA_Engines), which is
|
||||
* presumably stored in one or more internal buffers. This process can be done in several separate
|
||||
* transfers, as long as they don't exceed the size of the internal image buffer. This allows
|
||||
* flexibility in input strides.
|
||||
* - The input data is decoded into a YUV tuple. Several formats are suported, see the `InputFormat`
|
||||
* enum.
|
||||
* - The YUV tuple is converted, using fixed point calculations, to RGB. This step can be configured
|
||||
* using a set of coefficients to support different colorspace standards. See `CoefficientSet`.
|
||||
* - The strip can be optionally rotated 90, 180 or 270 degrees. Since each strip is processed
|
||||
* independently, this notably rotates each *strip*, not the entire image. This means that for 90
|
||||
* or 270 degree rotations, the output will be in terms of several 8 x height images, and for any
|
||||
* non-zero rotation the strips will have to be re-arranged so that the parts of the image will
|
||||
* not be shuffled together. This limitation makes this a feature of somewhat dubious utility. 90
|
||||
* or 270 degree rotations in images with non-even height don't seem to work properly.
|
||||
* - The data is converted to the output RGB format. See the `OutputFormat` enum.
|
||||
* - The data can be output either linearly line-by-line or in the swizzled 8x8 tile format used by
|
||||
* the PICA. This is decided by the `BlockAlignment` enum. If 8x8 alignment is used, then the
|
||||
* image must have a height divisible by 8. The image width must always be divisible by 8.
|
||||
* - The final data is then CDMAed out to main memory and the next image strip is processed. This
|
||||
* offers the same flexibility as the input stage.
|
||||
*
|
||||
* In this implementation, to avoid the combinatorial explosion of parameter combinations, common
|
||||
* intermediate formats are used and where possible tables or parameters are used instead of
|
||||
* diverging code paths to keep the amount of branches in check. Some steps are also merged to
|
||||
* increase efficiency.
|
||||
*
|
||||
* Output for all valid settings combinations matches hardware, however output in some edge-cases
|
||||
* differs:
|
||||
*
|
||||
* - `Block8x8` alignment with non-mod8 height produces different garbage patterns on the last
|
||||
* strip, especially when combined with rotation.
|
||||
* - Hardware, when using `Linear` alignment with a non-even height and 90 or 270 degree rotation
|
||||
* produces misaligned output on the last strip. This implmentation produces output with the
|
||||
* correct "expected" alignment.
|
||||
*
|
||||
* Hardware behaves strangely (doesn't fire the completion interrupt, for example) in these cases,
|
||||
* so they are believed to be invalid configurations anyway.
