| FUNCTION DESCRIPTION |
| |
| This function creates a table called BytesUsed that holds the value that |
| describes the number of bytes required to hold one frame worth of data in |
| the WMF (non-IF2) frame format. Each table entry is the sum of the frame |
| type byte and the number of bytes used up by the core speech data for each |
| 3GPP frame type. |

| 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) |
