ABSTRACT:
A computer system (100) comprises a processor (110), a memory (300), an interface (101) and peripheral devices (120-1, 120-2, 120-3). The interface has a pointer generator (160), a port (150), a decoder (170), and a parameter register (180). The port (150) transmits data words D(k) (380-k) from the memory (300) to the peripheral devices (120-1, 120-2, 120-3) or vice versa. Communication parameters are stored as parameter sets {P.sub.m } in parameter fields (185-m) of the parameter register (180). The decoder (170) selects a parameter set {P.sub.i } using from control words C(k) stored in the memory (300). Data queues can simultaneously be transmitted to two or more peripheral devices (120-1, 120-2, 120-3).
