changing this piece of c code to intrinsics

See more:

C

int shift = IF_INTERNAL_PREC - bitDepth;
   short offset = IF_INTERNAL_OFFS;
   offset += shift?(1 >> (shift - 1)):0;
   short maxVal = (1 >> bitDepth) - 1;
   short minVal = 0;
   //short val;
   for (row = 0; row < height; row++)
   {
     for (col = 0; col < width; col++)
     {
         
       short val = src[ col ];
       val = ( val + offset ) >> shift;
     
     
     
      if (val < minVal) val = minVal;
      if (val > maxVal) val = maxVal;
       dst[col] = val;
     }

I had written a intrinsics for the given c code
which is not correct. I am struck with If-else and assigning min val and max val to four short int and how to assisgn one short int value which is less or greater among the four short int as I am dealing with 16 bit values.

int shift = IF_INTERNAL_PREC - bitDepth;
short offset = IF_INTERNAL_OFFS;
offset += shift?(1 << (shift - 1)):0;
short maxVal = (1 << bitDepth) - 1;
short minVal = 0;
short val;
for (row = 0; row < height; row++)
{
  for (col = 0; col < width; col++)
  {


      val = ( src[col] + offset ) >> shift;

      dst[col]= (val > minVal) ? (val>maxVal)? maxVal:val :minVal;

  }

  src += srcStride;
  dst += dstStride;



}

Please help me as I am new with mmx intrinsics.
