+ FUNCTION NAME: Az_lsp
+------------------------------------------------------------------------------
+ INPUT AND OUTPUT DEFINITIONS FOR Az_lsp
+
+ Inputs:
+    a = predictor coefficients (Word16)
+    lsp = line spectral pairs (Word16)
+    old_lsp = old line spectral pairs (Word16)
+
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    pOverflow -> 1 if the operations in the function resulted in saturation.
+
+ Returns:
+    None.
+
+ Global Variables Used:
+    None.
+
+ Local Variables Needed:
+    None.
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function computes the LSPs from the LP coefficients.
+
+ The sum and difference filters are computed and divided by 1+z^{-1} and
+ 1-z^{-1}, respectively.
+
+     f1[i] = a[i] + a[11-i] - f1[i-1] ;   i=1,...,5
+     f2[i] = a[i] - a[11-i] + f2[i-1] ;   i=1,...,5
+
+ The roots of F1(z) and F2(z) are found using Chebyshev polynomial evaluation.
+ The polynomials are evaluated at 60 points regularly spaced in the
+ frequency domain. The sign change interval is subdivided 4 times to better
+ track the root. The LSPs are found in the cosine domain [1,-1].
+
+ If less than 10 roots are found, the LSPs from the past frame are used.
+

+ REQUIREMENTS
+
+ None.

+ FUNCTION DESCRIPTION
+
+ This function is a fractional integer division of two 32 bit numbers, the
+ numerator L_num and the denominator L_denom. The denominator is formed by
+ combining denom_hi and denom_lo. Note that denom_hi is a normalized numbers.
+ The numerator and denominator must be positive and the numerator must be
+ less than the denominator.
+
+ The division is done as follows:
+ 1. Find 1/L_denom by first approximating: approx = 1 / denom_hi.
+ 2. 1/L_denom = approx * (2.0 - L_denom * approx ).
+ 3. result = L_num * (1/L_denom).

+ FUNCTION DESCRIPTION
+
+ This function computes 1/sqrt(L_x), where L_x is positive.
+ If L_x is negative or zero, the result is 1 (3fff ffff).
+
+ The function 1/sqrt(L_x) is approximated by a table and linear
+ interpolation. The inverse square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If (30-exponent) is even then shift right once.
+    3- exponent = (30-exponent)/2  +1
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- L_y >>= exponent

+             in the range : 0x8000 0000 <= L_var1 <= 0x7fff ffff.

+ FUNCTION DESCRIPTION
+
+ This function arithmetically shifts the 32 bit input L_var1 right var2
+ positions with rounding. If var2 is negative, the function
+ arithmetically shifts L_var1 left by -var2 and zero fills the -var2 LSB of
+ the result. The result is saturated in case of underflows or overflows, i.e.,
+
+ - If var2 is greater than zero :
+    if (L_sub(L_shl(L_shr(L_var1,var2),1),L_shr(L_var1,sub(var2,1))))
+    is equal to zero
+    then

+    else
+        L_shr_r(L_var1,var2) = L_add(L_shr(L_var1,var2),1)
+ - If var2 is less than or equal to zero :
+    L_shr_r(L_var1,var2) = L_shr(L_var1,var2).

+ FUNCTION DESCRIPTION
+
+ The function Log2(L_x) calculates the logarithm of the normalized input
+ buffer L_x. The logarithm is approximated by a table and linear
+ interpolation. The following steps are used to compute Log2(L_x):
+
+ 1. exponent = 30 - norm_exponent
+ 2. i = bit25-b31 of L_x;  32<=i<=63  (because of normalization).
+ 3. a = bit10-b24
+ 4. i = i - 32
+ 5. fraction = table[i]<<16 - (table[i] - table[i+1]) * a * 2

+ FUNCTION DESCRIPTION
+
+ This function finds the polynomial F1(z) or F2(z) from the LSPs. If the LSP
+ vector is passed at address 0, F1(z) is computed and if it is passed at
+ address 1, F2(z) is computed.
+
+ This is performed by expanding the product polynomials:
+
+    F1(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=0,2,4,6,8
+    F2(z) =   product   ( 1 - 2 lsp[i] z^-1 + z^-2 )
+        i=1,3,5,7,9
+
+ where lsp[] is the LSP vector in the cosine domain.
+
+ The expansion is performed using the following recursion:
+
+    f[0] = 1
+    b = -2.0 * lsp[0]
+    f[1] = b
+    for i=2 to 5 do
+        b = -2.0 * lsp[2*i-2];
+        for j=i-1 down to 2 do
+            f[j] = f[j] + b*f[j-1] + f[j-2];
+        f[1] = f[1] + b;

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    var1 = 16 bit short signed integer (Word16) whose value falls in
+           the range : 0xffff 8000 <= var1 <= 0x0000 7fff.
+
+    var2 = 16 bit short signed integer (Word16) whose value falls in
+           the range : 0xffff 8000 <= var2 <= 0x0000 7fff.
+
+    pOverflow = pointer to overflow (Flag)
+
+ Outputs:
+    pOverflow -> 1 if the add operation resulted in overflow
+
+ Returns:

+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function performs the multiplication of var1 by var2 with rounding, and
+ gives a 16 bit result which is scaled, i.e.:
+    mult_r(var1,var2) = extract_l(L_shr(((var1 * var2) + 16384),15)) and  |

+ FUNCTION DESCRIPTION
+
+ PURPOSE:  Quantization of 2 sets of LSF parameters using 1st order MA
+           prediction and split by 5 matrix quantization (split-MQ)
+
+ DESCRIPTION:
+
+      p[i] = pred_factor*past_rq[i];   i=0,...,m-1
+      r1[i]= lsf1[i] - p[i];           i=0,...,m-1
+      r2[i]= lsf2[i] - p[i];           i=0,...,m-1
+ where:
+      lsf1[i]           1st mean-removed LSF vector.
+      lsf2[i]           2nd mean-removed LSF vector.
+      r1[i]             1st residual prediction vector.
+      r2[i]             2nd residual prediction vector.
+      past_r2q[i]       Past quantized residual (2nd vector).
+
+ The residual vectors r1[i] and r2[i] are jointly quantized using
+ split-MQ with 5 codebooks. Each 4th dimension submatrix contains 2
+ elements from each residual vector. The 5 submatrices are as follows:
+   {r1[0], r1[1], r2[0], r2[1]};  {r1[2], r1[3], r2[2], r2[3]};
+   {r1[4], r1[5], r2[4], r2[5]};  {r1[6], r1[7], r2[6], r2[7]};
+                  {r1[8], r1[9], r2[8], r2[9]}

+ FUNCTION DESCRIPTION
+
+ This is an implementation of decimation-in-time FFT algorithm for
+ real sequences.  The techniques used here can be found in several
+ books, e.g., i) Proakis and Manolakis, "Digital Signal Processing",
+ 2nd Edition, Chapter 9, and ii) W.H. Press et. al., "Numerical
+ Recipes in C", 2nd Ediiton, Chapter 12.
+
+ Input -  There is one input to this function:
+
+   1) An integer pointer to the input data array
+
+ Output - There is no return value.
+   The input data are replaced with transformed data.  If the
+   input is a real time domain sequence, it is replaced with
+   the complex FFT for positive frequencies.  The FFT value
+   for DC and the foldover frequency are combined to form the
+   first complex number in the array.  The remaining complex
+   numbers correspond to increasing frequencies.  If the input
+   is a complex frequency domain sequence arranged as above,
+   it is replaced with the corresponding time domain sequence.
+
+ Notes:
+
+   1) This function is designed to be a part of a VAD
+      algorithm that requires 128-point FFT of real
+      sequences.  This is achieved here through a 64-point
+      complex FFT.  Consequently, the FFT size information is
+      not transmitted explicitly.  However, some flexibility
+      is provided in the function to change the size of the
+      FFT by specifying the size information through "define"
+      statements.
+
+   2) The values of the complex sinusoids used in the FFT
+      algorithm are stored in a ROM table.
+
+   3) In the c_fft function, the FFT values are divided by
+      2 after each stage of computation thus dividing the
+      final FFT values by 64.  This is somewhat different
+          from the usual definition of FFT where the factor 1/N,
+          i.e., 1/64, used for the IFFT and not the FFT.  No factor
+          is used in the r_fft function.

+ books, e.g., i) Proakis and Manolakis, "Digital Signal Processing",
+ 2nd Edition, Chapter 9, and ii) W.H. Press et. al., "Numerical
+ Recipes in C", 2nd Ediiton, Chapter 12.
+
+ Input -  There is one input to this function:
+
+   1) An integer pointer to the input data array
+
+ Output - There is no return value.
+   The input data are replaced with transformed data.  If the
+   input is a real time domain sequence, it is replaced with
+   the complex FFT for positive frequencies.  The FFT value
+   for DC and the foldover frequency are combined to form the
+   first complex number in the array.  The remaining complex
+   numbers correspond to increasing frequencies.  If the input
+   is a complex frequency domain sequence arranged as above,
+   it is replaced with the corresponding time domain sequence.
+
+ Notes:
+
+   1) This function is designed to be a part of a VAD
+      algorithm that requires 128-point FFT of real
+      sequences.  This is achieved here through a 64-point
+      complex FFT.  Consequently, the FFT size information is
+      not transmitted explicitly.  However, some flexibility
+      is provided in the function to change the size of the
+      FFT by specifying the size information through "define"
+      statements.
+
+   2) The values of the complex sinusoids used in the FFT
+      algorithm are stored in a ROM table.
+
+   3) In the c_fft function, the FFT values are divided by
+      2 after each stage of computation thus dividing the
+      final FFT values by 64.  This is somewhat different
+          from the usual definition of FFT where the factor 1/N,
+          i.e., 1/64, used for the IFFT and not the FFT.  No factor
+          is used in the r_fft function.

+ INPUT AND OUTPUT DEFINITIONS
+
+ Inputs:
+    L_x = input value (Word32)
+    pExp = pointer to right shift to be applied to result
+    pOverflow = pointer to overflow flag
+
+ Outputs:
+    pOverflow -> if the Inv_sqrt operation resulted in an overflow.
+
+ Returns:
+    L_y = squareroot of L_x (Word32)
+
+ Global Variables Used:
+    None.
+
+ Local Variables Needed:
+    None.
+
+------------------------------------------------------------------------------
+ FUNCTION DESCRIPTION
+
+ This function computes sqrt(L_x),  where  L_x is positive.
+ If L_var is negative or zero, the result is 0
+
+ The function sqrt(L_x) is approximated by a table and linear
+ interpolation. The square root is computed using the
+ following steps:
+    1- Normalization of L_x.
+    2- If exponent is even then shift right once.
+    3- exponent = exponent/2
+    4- i = bit25-b31 of L_x;  16<=i<=63  because of normalization.
+    5- a = bit10-b24
+    6- i -=16
+    7- L_y = table[i]<<16 - (table[i] - table[i+1]) * a * 2
+    8- return L_y and exponent so caller can do denormalization
