Abstract: Access is frequently required between a central processing arrangement and a plurality of peripheral equipments each associated with buffer storage. Control of such access is provided using a local store which has, for each peripheral, two storage locations, one for the control word appropriate to the peripheral and the other as an additional data word buffer. In this way setting up an access is speeded as also is the freeing of common data highways.
