File: BASOP32.H v.2.3 - 30.Nov.2009
===========================================================================
ITU-T STL BASIC OPERATORS
GLOBAL FUNCTION PROTOTYPES
History:
26.Jan.00 v1.0 Incorporated to the STL from updated G.723.1/G.729
basic operator library (based on basic_op.h) and
G.723.1's basop.h.
05.Jul.00 v1.1 Added 32-bit shiftless mult/mac/msub operators
03 Nov 04 v2.0 Incorporation of new 32-bit / 40-bit / control
operators for the ITU-T Standard Tool Library as
described in Geneva, 20-30 January 2004 WP 3/16 Q10/16
TD 11 document and subsequent discussions on the
wp3audio@yahoogroups.com email reflector.
norm_s() weight reduced from 15 to 1.
norm_l() weight reduced from 30 to 1.
L_abs() weight reduced from 2 to 1.
L_add() weight reduced from 2 to 1.
L_negate() weight reduced from 2 to 1.
L_shl() weight reduced from 2 to 1.
L_shr() weight reduced from 2 to 1.
L_sub() weight reduced from 2 to 1.
mac_r() weight reduced from 2 to 1.
msu_r() weight reduced from 2 to 1.
mult_r() weight reduced from 2 to 1.
L_deposit_h() weight reduced from 2 to 1.
L_deposit_l() weight reduced from 2 to 1.
L_mls() weight of 5.
div_l() weight of 32.
i_mult() weight of 3.
30 Nov 09 v2.3 round() function is now round_fx().
saturate() is not referencable from outside application
13 Mar 12 Add Overflow2 flag for additional overflow checking.
