Multiple coupler for active computers including one master - uses bidirectional programmable input-output gate circuits

Abstract

Abstract A coupling for several active computing devices, one of which is a master and the rest slave units, involves couplers, address, control, and data highways combined to enable a synchronous data exchange using an interrupt method. It is of the simplest possible construction, low circuit complexity and high efficiency and makes extensive use of standardised component groups. Bidirectional programmable input/output gate circuits for each computer contain data, address, and control sections and are interconnected via highways. Special control circuits prevent accessing conflicts.
