Abstract
A gate unit is connected between a central processing unit and a storage means such as a drum or disc memory. A comparator unit is operative to store therein a data search item. In the data search mode, the gate means sequentially gates data items from the storage means into a buffer register having an output connected to an input of the comparator unit. The gate means is controlled to gate a data item in the buffer register to the central processing unit only when the data item corresponds to the search item stored in the comparator unit. The comparator unit may perform AND, OR, magnitude or any other type of comparison which is required.
