|

; // ----------
|
||||
; //
|
||||
; // This routine can use 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.
