CONTROLLER OF INTERBLOCK EXCHANGE CHANNEL Russian patent published in 2009 - IPC G06F13/24 

FIELD: physics, computer facilities.

SUBSTANCE: invention concerns computer facilities and can be used for data exchange between the control computer and exterior devices in a mode of real time. Controller of channel of interblock exchange contains interface of busbar of computer, generator of clock impulses, divider of frequency of impulses, time counter, timer, shaper of interruptions, guidance register, state register, buffer storage device, interface of channel of interblock exchange, OR element, trigger and key. In initial state the trigger is in state unity. The individual signal from a trigger exit arrives on a driving inlet of a key and resolves signal passage through a key from the second target line of the channel of an interblock exchange for a control output. If during transmission of the information frame the interface of the channel of an interblock exchange fixes an error (malfunction), on its second exit there will be an individual signal which through OR element will arrive on an inlet of dump of the trigger and will erect it in a zero state. As a result of the target signal of the trigger arriving on the driving inlet of key, will forbid signal passage through key from the first line of the channel of an interblock exchange for a control exit.

EFFECT: expansion of functionality of device at expense of introduction of function providing recording and the analysis of individual malfunctions at working off of transmission channels of the information.
