2012-08-13g723.1: do not bounce intermediate values via memoryMans Rullgard

2012-08-13g723.1: use saturating addition functionsMans Rullgard
Use saturating addition functions instead of 64-bit intermediates and separate clipping. This is much faster when dedicated instructions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-08-13g723.1: optimise scale_vector()Mans Rullgard
Firstly, nothing in this function can overflow 32 bits so the use of a 64-bit type is completely unnecessary. Secondly, the scale is either a power of two or 0x7fff. Doing separate loops for these cases avoids using multiplications. Finally, since only the number of bits, not the actual value, of the maximum value is needed, the bitwise or of all the values serves the purpose while being faster. It is worth noting that even if overflow could happen, it was not handled correctly anyway. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-08-13g723.1: remove useless uses of MUL64()Mans Rullgard
The operands in both cases are 16-bit so cannot overflow a 32-bit destination. In gain_scale() the inputs are reduced to 14-bit, so even the shift cannot overflow. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-08-13g723.1: remove unnecessary argument 'shift' from dot_product()Mans Rullgard
The 'shift' argument is always 1 so there is no need to pass it explicitly in every call. Signed-off-by: Mans Rullgard <mans@mansr.com>
