Class Information
Number: 710/111
Name: Electrical computers and digital data processing systems: input/output > Intrasystem connection (e.g., bus and bus transaction processing) > Bus access regulation > Rotational prioritizing (i.e., round robin)
Description: Subject matter including means or steps for granting bus access to all contending digital data processing system components one at a time in a predetermined order before any one digital data processing system components may again obtain the bus.
