    This is not a problem since this case cannot happen.
    Let me not bother you with the details but just say that I don't have range problems and my only problem is how to speed up this code.

      Code optimization of inner loop

      Dear all,

      I would appriciate any input you may have on how to optimize this line which appears in my most inner loop:

      *pG=(short)(((i nt)w1*V1+w2*V2+ w3*V3+w4*V4)/(w1+w2+w3+w4));

      w1,w2,w3,w4,V1, V2,V3,V4 are all short and the result is also short.
      If it makes any difference, all variables are positive and smaller than 4095.

      Thanks for any input,
      Eli.
