Abstract:
System comprising at least two integrated processors (P1 and P2). These two processors (P1 and P2) are operably connected via two bi-directional communication channels for exchanging information. For establishing the bi-directional communication channels, the system comprises a first processor bus (10) to which the first processor (P1) is connected, a first direct memory access unit (45), a first programmable unit (34), and a first shareable unit (13). The programmable unit (34) can be programmed by the first processor (P1). Also comprised is a second processor bus (20), the second processor (P2) being connectable to the second processor bus (20), a second direct memory access unit (35), and a second programmable unit (44). Said second programmable unit (44) is programmable by the second processor (P2).
Abstract:
The device includes two pressure rollers (24,25) mounted on their respective levers (20,21) and brought to bear upon two parallel shafts (36,37), for driving the tape in the forward and backward directions. The magnetic head is fitted to a carrier (2) which moves it into different positions with respect to the path of the tape. An adjustment lever (5), which is rotatable and/or slidable on the head carrier, is coupled to both of the roller levers and moves them into their alternative positions when the tape is reversed. The position of both levers is determined by that of the adjustment lever, in both directions.
Abstract:
The drive has a magnetic head (5) fixed in an opening (4a) of a carrier (4) which floats at one end of a supporting lever (2) on a chassis board (1). For the various operations the head is movable into different positions with respect to the path of the magnetic tape (6) between parallel shafts (7,8). The carrier is pivotable within predetermined limits on the lever and can also slide in a direction approximately at right angles to the tape, so that the head can be oriented in at least two positions parallel to the tape.
