| 54 | // Overview of operation | |
| 55 | // ============================================================== | |
| 56 | // | |
| 57 | // There are 7 paths: | |
| 58 | // 1. x = 0.0 | |
| 59 | // Return asinh(x) = 0.0 | |
| 60 | // | |
| 61 | // 2. 0.0 <|x| < 2^(-3) | |
| 62 | // Return asinh(x) = POL13(x), | |
| 63 | // where POL13(x) = (x^2*C13 + ...)*x^2 + C5)*x^2 + C3)*x^3 + x | |
| 64 | // | |
| 65 | // 3. 2^(-3) <= |x| < 2^63 | |
| 66 | // Return asinh(x) = sign(x)*(log(|x| + sqrt(x^2 + 1.0))) | |
| 67 | // To compute x + sqrt(x^2 + 1.0) modified Newton Raphson method is used | |
| 68 | // (3 iterations) | |
| 69 | // Algorithm description for log function see below. | |
| 70 | // | |
| 71 | // 4. 2^63 <= |x| < +INF | |
| 72 | // Return asinh(x) = sign(x)*log(2*|x|) | |

| 74 | // | |
| 75 | // 5. x = INF | |
| 76 | // Return asinh(x) = INF | |
| 77 | // | |
| 78 | // 6. x = [S,Q]NaN | |
| 79 | // Return asinh(x) = QNaN | |
| 80 | // | |
| 81 | // 7. x = denormal | |
| 82 | // Return asinh(x) = x correctly rounded | |
| 83 | // | |
| 84 | //============================================================== | |
| 85 | // Algorithm Description for log(x) function | |
| 86 | // Below we are using the fact that inequality x - 1.0 > 2^(-6) is always | |
| 87 | // true for this asinh implementation | |
| 88 | // | |
| 89 | // Consider x = 2^N 1.f1 f2 f3 f4...f63 | |
| 90 | // Log(x) = log(frcpa(x) x/frcpa(x)) | |
| 91 | // = log(1/frcpa(x)) + log(frcpa(x) x) | |
| 92 | // = -log(frcpa(x)) + log(frcpa(x) x) | |
| 93 | // | |
| 94 | // frcpa(x) = 2^-N frcpa((1.f1 f2 ... f63) | |
| 95 | // | |
| 96 | // -log(frcpa(x)) = -log(C) | |
| 97 | // = -log(2^-N) - log(frcpa(1.f1 f2 ... f63)) | |
| 98 | // | |
| 99 | // -log(frcpa(x)) = -log(C) | |
| 100 | // = +Nlog2 - log(frcpa(1.f1 f2 ... f63)) | |
| 101 | // | |
| 102 | // -log(frcpa(x)) = -log(C) | |
| 103 | // = +Nlog2 + log(frcpa(1.f1 f2 ... f63)) | |
| 104 | // | |
| 105 | // Log(x) = log(1/frcpa(x)) + log(frcpa(x) x) | |
| 106 | // | |
| 107 | // Log(x) = +Nlog2 + log(1./frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x) | |
| 108 | // Log(x) = +Nlog2 - log(/frcpa(1.f1 f2 ... f63)) + log(frcpa(x) x) | |
| 109 | // Log(x) = +Nlog2 + T + log(frcpa(x) x) | |
| 110 | // | |
| 111 | // Log(x) = +Nlog2 + T + log(C x) | |
| 112 | // | |
| 113 | // Cx = 1 + r | |
| 114 | // | |
| 115 | // Log(x) = +Nlog2 + T + log(1+r) | |
| 116 | // Log(x) = +Nlog2 + T + Series( r - r^2/2 + r^3/3 - r^4/4 ....) | |
| 117 | // | |
| 118 | // 1.f1 f2 ... f8 has 256 entries. | |
| 119 | // They are 1 + k/2^8, k = 0 ... 255 | |
| 120 | // These 256 values are the table entries. | |
| 121 | // | |
| 122 | // Implementation | |
| 123 | //============================================================== | |
| 124 | // C = frcpa(x) | |
| 125 | // r = C * x - 1 | |
| 126 | // | |
| 127 | // Form rseries = r + P1*r^2 + P2*r^3 + P3*r^4 + P4*r^5 + P5*r^6 | |
| 128 | // | |
| 129 | // x = f * 2*n where f is 1.f_1f_2f_3....f_63 | |
| 130 | // Nfloat = float(n) where n is the true unbiased exponent | |
| 131 | // pre-index = f_1f_2....f_8 | |
| 132 | // index = pre_index * 16 | |
| 133 | // get the dxt table entry at index + offset = T | |
| 134 | // | |
| 135 | // result = (T + Nfloat * log(2)) + rseries | |
| 136 | // | |
| 137 | // The T table is calculated as follows | |
| 138 | // Form x_k = 1 + k/2^8 where k goes from 0... 255 | |
| 139 | // y_k = frcpa(x_k) | |
| 140 | // log(1/y_k) in quad and round to double-extended | |
