| REVISION HISTORY |
| |
| Description: Moved WMFBytesUsed and IF2BytesUsed tables from gsmamr_enc.h. |
| Changed their type definition to 'const int'. Renamed tables to |
| WmfEncBytesPerFrame and If2EncBytesPerFrame. |
| |
| Description: Added #ifdef __cplusplus and removed "extern" from table |
| definition. |
| |
| Description: Put "extern" back. |

| RESOURCES USED |
| When the code is written for a specific target processor the |
| the resources used should be documented below. |
| |
| STACK USAGE: [stack count for this module] + [variable to represent |
| stack usage for each subroutine called] |
| |
| where: [stack usage variable] = stack usage for [subroutine |
| name] (see [filename].ext) |
| |
| DATA MEMORY USED: x words |
| |
| PROGRAM MEMORY USED: x words |
| |
| CLOCK CYCLES: [cycle count equation for this module] + [variable |
| used to represent cycle count for each subroutine |
| called] |
| |
| where: [cycle count variable] = cycle count for [subroutine |
| name] (see [filename].ext) |
