/*
YUV420 to RGB565 conversion. This routine takes a YUV 420 planar macroblock
and converts it to RGB565. R:5 bits, G:6 bits, B:5 bits.. packed into shorts.


The following calculation is used for the conversion:

r = clipz((y-oy)*cy + crv*(v-128))
g = clipz((y-oy)*cy + cgv*(v-128) + cgu*(u-128))
b = clipz((y-oy)*cy + cbu*(u-128))

y,u,v are prescaled by a factor of 4 i.e. left-shifted to gain precision.


New factorization to eliminate the truncation error which was
occurring due to the byteop3p.


1) Use the bytop16m to subtract quad bytes we use this in U8 this
then so the offsets need to be renormalized to 8bits.

2) Scale operands up by a factor of 4 not 8 because Blackfin
multiplies include a shift.

3) Compute into the accumulators cy*yx0, cy*yx1.

4) Compute each of the linear equations:
r = clipz((y - oy) * cy + crv * (v - 128))

g = clipz((y - oy) * cy + cgv * (v - 128) + cgu * (u - 128))

b = clipz((y - oy) * cy + cbu * (u - 128))

Reuse of the accumulators requires that we actually multiply
twice once with addition and the second time with a subtraction.

Because of this we need to compute the equations in the order R B
then G saving the writes for B in the case of 24/32 bit color
formats.

API: yuv2rgb_kind (uint8_t *Y, uint8_t *U, uint8_t *V, int *out,
int dW, uint32_t *coeffs);

A B
--- ---
i2 = cb i3 = cr
i1 = coeff i0 = y

Where coeffs have the following layout in memory.

uint32_t oy,oc,zero,cy,crv,rmask,cbu,bmask,cgu,cgv;

coeffs is a pointer to oy.

The {rgb} masks are only utilized by the 565 packing algorithm. Note the data
replication is used to simplify the internal algorithms for the dual Mac
architecture of BlackFin.

All routines are exported with _ff_bfin_ as a symbol prefix.

Rough performance gain compared against -O3:

2779809/1484290 187.28%

which translates to ~33c/pel to ~57c/pel for the reference vs 17.5
c/pel for the optimized implementations. Not sure why there is such a
huge variation on the reference codes on Blackfin I guess it must have
to do with the memory system.

/*
Convert I420 YV12 to RGB in various formats,
it rejects images that are not in 420 formats,
it rejects images that don't have widths of multiples of 16,
it rejects images that don't have heights of multiples of 2.
Reject defers to C simulation code.

Lots of optimizations to be done here.

1. Need to fix saturation code. I just couldn't get it to fly with packs
and adds, so we currently use max/min to clip.

2. The inefficient use of chroma loading needs a bit of brushing up.

3. Analysis of pipeline stalls needs to be done. Use shark to identify
pipeline stalls.


MODIFIED to calculate coeffs from currently selected color space.
MODIFIED core to be a macro where you specify the output format.
ADDED UYVY conversion which is never called due to some thing in swscale.
CORRECTED algorithim selection to be strict on input formats.
ADDED runtime detection of AltiVec.

ADDED altivec_yuv2packedX vertical scl + RGB converter

March 27,2004
PERFORMANCE ANALYSIS

The C version uses 25% of the processor or ~250Mips for D1 video rawvideo
used as test.
The AltiVec version uses 10% of the processor or ~100Mips for D1 video
same sequence.

720 * 480 * 30 ~10MPS

so we have roughly 10 clocks per pixel. This is too high, something has
to be wrong.

OPTIMIZED clip codes to utilize vec_max and vec_packs removing the
need for vec_min.

OPTIMIZED DST OUTPUT cache/DMA controls. We are pretty much guaranteed to have
the input video frame, it was just decompressed so it probably resides in L1
caches. However, we are creating the output video stream. This needs to use the
DSTST instruction to optimize for the cache. We couple this with the fact that
we are not going to be visiting the input buffer again so we mark it Least
Recently Used. This shaves 25% of the processor cycles off.

Now memcpy is the largest mips consumer in the system, probably due
to the inefficient X11 stuff.

GL libraries seem to be very slow on this machine 1.33Ghz PB running
Jaguar, this is not the case for my 1Ghz PB. I thought it might be
a versioning issue, however I have libGL.1.2.dylib for both
machines. (We need to figure this out now.)

GL2 libraries work now with patch for RGB32.

NOTE: quartz vo driver ARGB32_to_RGB24 consumes 30% of the processor.

Integrated luma prescaling adjustment for saturation/contrast/brightness
adjustment.
