| REVISION HISTORY |
| |
| Description: Added BytesUsed table so that the code can allow for padding |
| at the end of each frame. |
| |
| Description: Removed function prototypes for getbits, putbits, |
| put_frame_header_in, and get_frame_header_off. Removed |
| basicop_malloc.h and replaced it with typedef.h in the include |
| section. Fixed table entries for various SID modes. Removed |
| #defines because they are not used by AMRDecode function. |
| Removed tables not used by AMRDecode function. |
| |
| Description: The data type Speech_Decode_FrameState is now being passed into |
| this function as a void pointer rather than a structure of type |
| Speech_Decode_FrameState. |
| |
| Description: The variable decoder_state was renamed to state_data. |
| |
| Description: Updated function prototype and header template. |
| |
| Description: Added mode.h and frame_type_3gpp.h to include section, and |
| removed sp_dec.h. |
| |
| Description: Removed definition of Changed BytesThisFrame[] table. Added |
| extern declaration for BytesThisFrame[] table. |
| |
| Description: Added #define for WMF and IF2. Updated function prototype. |
| |
| Description: Moved input format #defines and BytesThisFrame table to |
| dec_input_format_tab.h and dec_input_format_tab.c, respectively. |
| Updated function prototype. |
| |
| Description: Updated function prototype of AMRDecode due to the removal of |
| *prev_mode_ptr. Added extern of If2BytesPerFrame |
| |
| Description: Added #defines for WMF, IF2, and ETS input formats. |
| |
| Description: Changed WmfBytesPerFrame to WmfDecBytesPerFrame, and |
| If2BytesPerFrame to If2DecBytesPerFrame. |
| |
| Description: Renamed #defines for input format types to make it unique to the |
| decoder. |
| |
| Description: Replaced "int" and/or "char" with OSCL defined types. |
| |
| Description: Moved _cplusplus #ifdef after Include section. |

| INCLUDE DESCRIPTION |
| |
| This file contains all the constant definitions and prototype definitions |
| needed by the norm_s function. |
