FIELD: computer engineering. SUBSTANCE: this equipment is designed for multimachine computer systems and local computer networks for control over access to common line. Equipment has channels each composed of counters 1, 2, multiplexers 3,4, comparison circuit 5, flip-flops 6-9, AND gates 10,11, OR gates 12. 13, register 14. Main feature of invention lies in following procedure: if priority code of user coincides with code of its ordinal number and generation of priority code into main line starts from the more significant digit then each following digit of priority code can be sent into main line in the course of shorter time than the preceding one. EFFECT: enhanced productivity of equipment thanks to reduction of time spent on arbitration of requirements. 1 dwg
