FIELD: automatics and computer engineering; information input, which defines the external device, working with computer. ^ SUBSTANCE: device contains commutator, storage device, two counters, synchronizer, three gates. Address inputs of commutator and storage device are connected to each other and to byte outputs of counter, which continuously changes its state influenced by clock signal. Each counter state corresponds to the number of external device and to information written in storage device, which defines this external device. Address digit count of storage device is greater than commutator address digit count by one. That is, each external device has an identifier of two words, which is passed to computer during current query cycle. ^ EFFECT: increased transferred information quantity during current external devices query cycle. ^ 2 cl, 3 dwg |
