/ / Each horizontal filter result is formed by the sum of up to eight
/ / multiplications by filter values and then a shift . Although both the
/ / inputs and filters are loaded as int16 , the input data is at most bd
/ / bits and the filters are at most 8 bits each . Additionally since we
/ / know all possible filter values we know that the sum of absolute
/ / filter values will fit in at most 9 bits . With this in mind we can
/ / conclude that the sum of each filter application will fit in bd + 9
/ / bits . The shift following the summation is ROUND0_BITS ( which is 3 ) ,
/ / + 2 for 12 - bit , which gives us a final storage of :
/ / bd = = 8 : ( 8 + 9 ) - 3 = > 14 bits
/ / bd = = 10 : ( 10 + 9 ) - 3 = > 16 bits
/ / bd = = 12 : ( 12 + 9 ) - 5 = > 16 bits
/ / So it is safe to use int16x8_t as the intermediate storage type here .
