87 FUNCTION NAME: log2()
93 pExponent = pointer to the integer part of Log2 of type Word16 whose
95 pFraction = pointer to the fractional part of Log2 of type Word16
101 pExponent -> integer part of the newly calculated Log2
102 pFraction -> fractional part of the newly calculated Log2
103 pOverflow -> 1 if the log2() operation resulted in saturation

log2.c 19 * File : log2.c *
20 * Purpose : Computes log2(L_x) *
24 #include "log2.h"
34 #include "log2_tab.h" /* Table for Log2() */
40 * PURPOSE: Computes log2(L_x, exp), where L_x is positive and
45 * The function Log2(L_x) is approximated by a table and linear
46 * interpolation. The following steps are used to compute Log2(L_x)
59 Word16 *exponent, /* (o) : Integer part of Log2. (range: 0<=val<=30) */
60 Word16 *fraction /* (o) : Fractional part of Log2. (range: 0<=val<1) */
