ABSTRACT:
A stored logic Boolean function generator having a control word storage coupled to a control block for selectively configuring the control block into logic circuits for simulating either a logical AND circuit or a logical OR circuit for operating on binary signals. At least two external addressable binary signal stores are coupled to the control block. The two external addressable stores alternately and oppositely serve as source and destination storage devices for binary signals which are operated upon by the control block. One of the addressable stores serves as a source of binary signals which are supplied to the control block and operated upon by the logical circuit simulated therein. The results of the logical manipulation are stored in the other of the externally addressable stores which thus serves as a destination storage device. The control block is reconfigured according to the next successive control word stored in the control word storage and the flow of binary data through the control block is reversed such that the former destination store serves as the source of binary signals to the control block and the former source store serves as the destination for the control block. The binary data is continually circulated through the control block until the sequence of logical operations stored in the control word storage has been completed and the predetermined logical function performed.
