[XviD-devel] other FDCT with fewer multiplications

[skal]

	Hi,

	about the text in 2dDCT.zip: it's rather cryptic, without
	the original paper. So far, it seems that 1 mult (the one
	by r(4) = sqrt(2)) has disappeared. But 1 mult less is
	not everything. More crucial is the data flow schematic,
	as soon as precision is concerned. So i should be interesting
	to have the original paper, sure.

	bye,

(for the story: Thomas Lane, author of the first jpeg lib, *added*
some multiplications in the DCT, in order to better "spread" the
rounding errors around various data paths)
