| 15 ; * Notes: | |
| 16 ; * | |
| 17 ; * This implementation makes use of 16 bit fixed point version of two multiply | |
| 18 ; * constants: | |
| 19 ; * 1. sqrt(2) * cos (pi/8) | |
| 20 ; * 2. sqrt(2) * sin (pi/8) | |
| 21 ; * Because the first constant is bigger than 1, to maintain the same 16 bit | |
| 22 ; * fixed point precision as the second one, we use a trick of | |
| 23 ; * x * a = x + x*(a-1) | |
| 24 ; * so | |
| 25 ; * x * sqrt(2) * cos (pi/8) = x + x * (sqrt(2) *cos(pi/8)-1). | |
| 26 ; * | |
| 27 ; * For the second constant, because of the 16bit version is 35468, which | |
| 28 ; * is bigger than 32768, in signed 16 bit multiply, it becomes a negative | |
| 29 ; * number. | |
| 30 ; * (x * (unsigned)35468 >> 16) = x * (signed)35468 >> 16 + x | |
