For consistency with idct function names.

|
|
Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.
Change-Id: I2d95fdcbba96aaa0ed24a80870cb38f53487a97d
|
|
Also renaming dest_stride to stride in some places.

This commit reworked the unit test for 8x8 forward transform. It
allows scalability to cover various implemented versions.

This commit completes the per coefficient accuracy check and memory
overflow check for SSE2 and other implemented versions of 16x16
transform.

This commit refactors the 16x16 transform unit test. It enables the
test on all implemented versions of forward and inverse 16x16 transform
modules.

Suggested by James Zern to clear out cpplint warnings for all unit
test code.

Make the new test module comply to the unit test rules.

The mix use of double type and simd code caused invalid values stored
in double variables, further caused unit tests to fail. The failures
were only observed on x86-win32-vs9 build with vs2008.

Unit tests on the functional accuracy of forward ADST/DCT.

This patch eliminates the intermediate diff buffer usage by
combining the short idct and the add residual into one function.
The encoder can use the same code as well.

This commit added pre/post scaling for first half of fDCT16x16 to
reduce error, by simulation of 100,000 blocks for random inputs,
the average sse reduced from 2.1/block to 0.0498/block.
also enabled tests for 16x16 fDCT and iDCT

additionally dct.h was removed; declare the _c functions that are used
in the tests. the TODO for conversion to parameterized tests still
remains.

The commit replaces run-time initialization of cosine constants with
static constant values, which provides ~30% relief on slow speed. The
real solution, however will be to implement integer versions of those
functions that current use float/double.
