-// fdctam32.c - AP922 MMX(3D-Now) forward-DCT
-// ----------
-// Intel Application Note AP-922 - fast, precise implementation of DCT
-// http://developer.intel.com/vtune/cbts/appnotes.htm
-// ----------
-//
-// This routine uses a 3D-Now/MMX enhancement to increase the
-// accuracy of the fdct_col_4 macro. The dct_col function uses 3D-Now's
-// PMHULHRW instead of MMX's PMHULHW(and POR). The substitution improves
-// accuracy very slightly with performance penalty. If the target CPU
-// does not support 3D-Now, then this function cannot be executed.
-// fdctmm32.c contains the standard MMX implementation of AP-922.
-//
-// For a fast, precise MMX implementation of inverse-DCT
-// visit http://www.elecard.com/peter
-//
-// v1.0 07/22/2000 (initial release)
-// Initial release of AP922 MMX(3D-Now) forward_DCT.
-// This code was tested with Visual C++ 6.0Pro + service_pack4 +
-// processor_pack_beta! If you have the processor_pack_beta, you can
-// remove the #include for amd3dx.h, and substitute the 'normal'
-// assembly lines for the macro'd versions. Otherwise, this
-// code should compile 'as is', under Visual C++ 6.0 Pro.
