LDF question

I am working on the implementation of FIR filter with adsp-2191. My VisualDSP++ is 3.0.
The ldf file, which I created for this project is:

 

// define architecture's processor
ARCHITECTURE(ADSP-2191)

// assign directory where can search for object and library files
SEARCH_DIR ($ADI_DSP\219x\lib; Work\FIR)

// include all of library and object files in assigned directory
$OBJECTS = $COMMAND_LINE_OBJECTS;

// output the map file
MAP(FIR.map)

// define the memory model
MEMORY
{ 
   mem_ivt    { TYPE(PM RAM) START(0x000000) END(0x000239) WIDTH(24) }
   mem_pmcode { TYPE(PM RAM) START(0x000240) END(0x007f38) WIDTH(24) }
   mem_pmdata { TYPE(PM RAM) START(0x007f39) END(0x007fff) WIDTH(24) }
   mem_dmdata { TYPE(DM RAM) START(0x008000) END(0x00ffff) WIDTH(16) }
}

// specify the processor of DSP system
PROCESSOR p0
{

// specify the name of dxe file
   OUTPUT ( $COMMAND_LINE_OUTPUT_FILE )

// specify the placement of input sections into output sections
// and the placement of output sections into memory
   SECTIONS
      { dxe_ivt     {INPUT_SECTIONS($OBJECTS(seg_ivt))}    > mem_ivt
        dxe_pmcode  {INPUT_SECTIONS($OBJECTS(seg_pmcode))} > mem_pmcode
        dxe_pmdata  {INPUT_SECTIONS($OBJECTS(seg_pmdata))} > mem_pmdata
        dxe_dmdata  {INPUT_SECTIONS($OBJECTS(seg_dmdata))} > mem_dmdata
      }
}

 

When I link the project everithing looks fine and complete, but the map file show
that the width of memory segments are different from those which I desire. The follow is map file:

What is wrong and if everything about my ldf file is fine, because this is my first dsp project?

Best Regards,
