Abstract
Round-robin arbitration circuit selects in clock cycle channel contending for arbitration; each arbitrated channel having channel number in sequence of channel numbers. Channel is designated as currently arbitrated; designated channel having designated number. Channels are masked from arbitration with designated channel, such that designated and unmasked channels are arbitrated to select channel. Channels having numbers sequenced after designated number are masked from arbitration, and channels having, numbers sequenced earlier than designated are also masked from arbitration. During subsequent cycle, designated channel is shifted to next channel in sequence of channel numbers by incrementing designated number. When designated number is last in sequence, designated channel is shifted to next having first number in sequence.
