For the temporary storage of instruction words read out of an instruction memory, an arrangement is used of one of a plurality of buffer memories (20 to 23) which are addressed for writing in and for reading out by a cyclically operating write counter (26) and a cyclically operating read counter (27). A monitoring circuit (28) controlling both counters (26,27) prevents the write counter (26) from overtaking the read counter (27).
