Each table entry is the sum of the frame 78 type byte and the number of bytes used up by the core speech data for each 79 3GPP frame type. 80 81 ------------------------------------------------------------------------------ 82 REQUIREMENTS 83 84 None 85 86 ------------------------------------------------------------------------------ 87 REFERENCES 88 89 [1] "AMR Speech Codec Frame Structure", 3GPP TS 26.101 version 4.1.0 90 Release 4, June 2001, page 13. 91 92 ------------------------------------------------------------------------------ 93 PSEUDO-CODE 94 95 96 ------------------------------------------------------------------------------ 97 RESOURCES USED 98 When the code is written for a specific target processor the 99 the resources used should be documented below. 100 101 STACK USAGE: [stack count for this module] + [variable to represent 102 stack usage for each subroutine called] 103 104 where: [stack usage variable] = stack usage for [subroutine 105 name] (see [filename].ext) 106 107 DATA MEMORY USED: x words 108 109 PROGRAM MEMORY USED: x words 110 111 CLOCK CYCLES: [cycle count equation for this module] + [variable 112 used to represent cycle count for each subroutine 113 called] 114 115 where: [cycle count variable] = cycle count for [subroutine 116 name] (see [filename].ext) 117 118 ------------------------------------------------------------------------------ 119 */ 120 121 122 /*---------------------------------------------------------------------------- 123 ; INCLUDES 124 ----------------------------------------------------------------------------*/ 125 #include "typedef.h" 126 127 /*--------------------------------------------------------------------------*/ 128 #ifdef __cplusplus 129 extern "C" 130 { 131 #endif 132 133 /*---------------------------------------------------------------------------- 134 ; MACROS 135 ; Define module specific macros here 136 ----------------------------------------------------------------------------*/ 137 138 139 /*---------------------------------------------------------------------------- 140 ; DEFINES 141 ; Include all pre-processor statements here.
