Apparatus for controlling site adjustment of shift grouped data

An apparatus comprising: a first storage area operable to have stored therein a first packed data containing at least an A 1 , an A 2 , an A 3 , and an A 4 element; a second storage area operable to have stored therein a second packed data containing at least a B 1 , a B 2 , a B 3 , and a B 4 element; a multiply circuit including a first multiplier coupled to said first storage area to receive said A 1 and coupled to said second storage area to receive said B 1 ; a second multiplier coupled to said first storage area to receive said A 2 and coupled to said second storage are to receive said B 2 ; a third multiplier coupled to said first storage area to receive said A 3 and coupled to said second storage area to receive said B 3 ; a fourth multiplier coupled to said first storage area to receive said A 4 and coupled to said second storage area to receive said B 4 ; a first adder coupled to said first multiplier and said second multiplier; a second adder coupled to said third multiplier and said fourth multipli
