Abstract
Transfers of information items between a memory array and different processing units of a digital data processing system are managed. Interface unit DIM connected between the system memory array and coupling bus BUSA for the different processing units of the system, comprises buffers PB, RBO, RB1, respectively associated with circuits CA2, CA1 and CA3 for aligning information items. Transfers of information items relating to instructions and data pass through these buffers. The transfers are automatic as a function of space available in these buffers. The framing and length of the information items are controlled automatically by microfunctions which greatly simplify operations for the microprogrammer for the information items which are octet aligned and of variable length.
