Hello!

I using WinAVR 20090313 and ATMega32.
I write code for time critical application.
There is a moving average filter algorithm.

    unsigned char data    = 0;
    unsigned char i       = 0;
    unsigned char mafinit = 0;
    unsigned int  mafsum  = 0;
    unsigned char mafdata[16];

    if (!mafinit)
    {
      for (i = 0; i < 16; i++)
        mafdata[i] = data;
      mafinit = 1;
    }

    for (i = 0; i < 15; i++)
    {
      mafdata[i] = mafdata[i+1];
      mafsum += mafdata[i];
    }
    mafdata[15] = data;
    mafsum += data;
    data = mafsum / 16;

Are there any ways to speedup algorithm?
