+*
+* OSF only defined if the current platform is an Alpha
+* PC only defined if the current platform is a PC
+* SUN only defined if the current platform is a Sun

+* Description:
+*-----------------------------------------------------------------------*
+* Compute the ISPs from the LPC coefficients (order=M) *
+*-----------------------------------------------------------------------*
+* *
+* The ISPs are the roots of the two polynomials F1(z) and F2(z) *
+* defined as *
+* F1(z) = A(z) + z^-m A(z^-1) *
+* and F2(z) = A(z) - z^-m A(z^-1) *
+* *
+* For a even order m=2n, F1(z) has M/2 conjugate roots on the unit *
+* circle and F2(z) has M/2-1 conjugate roots on the unit circle in *
+* addition to two roots at 0 and pi. *
+* *
+* For a 16th order LP analysis, F1(z) and F2(z) can be written as *
+* *
+* F1(z) = (1 + a[M]) PRODUCT (1 - 2 cos(w_i) z^-1 + z^-2 ) *
+* i=0,2,4,6,8,10,12,14 *
+* *
+* F2(z) = (1 - a[M]) (1 - z^-2) PRODUCT (1 - 2 cos(w_i) z^-1 + z^-2 ) *
+* i=1,3,5,7,9,11,13 *
+* *
+* The ISPs are the M-1 frequencies w_i, i=0...M-2 plus the last *
+* predictor coefficient a[M]. *

+ * *
+ * END *
+ * *
+ * Remarks on the dynamics of the calculations. *
+ * *
+ * The numbers used are in double precision in the following format : *
+ * A = AH <<16 + AL<<1. AH and AL are 16 bit signed integers. *
+ * Since the LSB's also contain a sign bit, this format does not *
+ * correspond to standard 32 bit integers. We use this format since *
+ * it allows fast execution of multiplications and divisions. *
+ * *
+ * "DPF" will refer to this special format in the following text. *
+ * See oper_32b.c *
+ * *
+ * The R[i] were normalized in routine AUTO (hence, R[i] < 1.0). *
+ * The K[i] and Alpha are theoretically < 1.0. *
+ * The A[i], for a sampling frequency of 8 kHz, are in practice *
+ * always inferior to 16.0. *
+ * *
+ * These characteristics allow straigthforward fixed-point *
+ * implementation. We choose to represent the parameters as *
+ * follows : *
+ * *
+ * R[i] Q31 +- .99.. *
+ * K[i] Q31 +- .99.. *
+ * Alpha Normalized -> mantissa in Q31 plus exponent *
+ * A[i] Q27 +- 15.999.. *
+ * *
+ * The additions are performed in 32 bit. For the summation used *
+ * to calculate the K[i], we multiply numbers in Q31 by numbers *
+ * in Q27, with the result of the multiplications in Q27, *
+ * resulting in a dynamic of +- 16. This is sufficient to avoid *
+ * overflow, since the final result of the summation is *
+ * necessarily < 1.0 as both the K[i] and Alpha are *
+ * theoretically < 1.0. *
