Abstract
In a data processing system a control device for an intermediate memory during a bulk data transport between two data devices. A first data device addresses a number of descriptor signals. Each descriptor signal indicates another descriptor signal, so that a sequence is formed which is cyclically coupled end-around. The descriptor signals indicate either a memory section or a branch to a remote address in the memory. The memory sections used may thus be distributed throughout the memory. Additional descriptor signals indicate, in a direct or indirect manner, a descriptor signal of the sequence for each of the two data devices. A handshake by way of signal bits is present at the level of the memory sections.
