BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention is directed to a connection network for adjustable connection of circuit arrangements, particularly programmable circuit arrangements, whereby every circuit arrangement can be transmitter or receiver. It is to be understood that the term "circuit arrangement" as used herein refers to a circuit element such as a programmable logic array (PLA).
It is required for some applications that a plurality of circuit arrangements be capable of being adjustably connected to one another. Each of these circuit arrangements can thereby be transmitter or receiver. This can be the case when a plurality of programmable circuits, abbreviated as PLA, are combined in a sequential logic system. Such programmable circuits contain an AND level and an OR level. The operation of the input signals in accord with a function table stored in the AND level ensues in the AND level. These operation results of the AND level that are also referred to as product terms, are supplied to the OR level and are operated there according to the function table contained in the OR level to form what are referred to as sum terms. The sum terms are output at the outputs of the OR level. Such a PLA has input lines that lead to the AND level and output lines that lead out from the OR level available to it. The structure of a programmable circuit arrangement can also be such that the AND level and the OR level are combined and it is possible to define by programming whether the lines leading into the programmable circuit arrangement--referred to as data lines in future--should be input lines or output lines.
SUMMARY OF THE INVENTION
The object underlying the invention is comprised in specifying a connection network for the adjustable connection of circuit arrangements that operate either as transmitter or as receiver. In a connection network of the species initially recited, this object is achieved in accord with the characterizing of patent claim 1.
The connection network is based on the principle of the bidirectional PLA, i.e. on the principle of a programmable circuit arrangement, whereby the lines employed as data lines can be set both as input line as well as output line with the assistance of a control signal. The connection of the data lines within the connection matrix ensues with the assistance of the adjustment matrix.
The advantage of this connection network is to be seen therein that every data line can be connected to every data line by programming the switching elements in the matrix in accord with a connection table and, moreover, the direction of the data transmission can be defined.
BRIEF DESCRIPTION OF THE DRAWINGS
Other improvements of the invention derive from the subclaims. The invention shall be set forth further with reference to exemplary embodiments that are shown in the figures. Shown are:

FIG. 2 a further block circuit diagram of the connection network;
FIG. 3 a fundamental circuit diagram of the matrix employed in the connection network;
FIG. 4 a wiring diagram of the matrix;
FIG. 5 and FIG. 6 examples of a programmed matrix;
FIG. 7, 8 examples of the connection setup between two circuit arrangements;
FIG. 9, 10 further examples of the connection of circuit arrangements with the assistance of the connection network.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 yields a block circuit diagram wherein four circuit arrangements ULB1 through ULB4 can be connected to one another via a connection network VN. Bidirectional, programmable circuit arrangements can be provided, by way of example, as circuit arrangements ULB. These programmable circuit arrangements have lines on which signals X are supplied or taken and have terminals A that are to be connected to one another via the connection network VN. Data transmission lines therefore lead from the terminals A of the programmable circuit arrangements ULB to the connection network VN. The connection network VN is constructed such that th
