Abstract
Method and structures for performing round robin priority selection receive an input vector into an input port. The methods and structures group the bits of the input vector into groups of bits and supply the groups of bits to round robin priority selectors. Then, the methods and structures simultaneously identify an individual group priority bit within each group of bits based on the starting bit location, using the round robin priority selectors. The methods and structures also choose, using the group selector, a round robin priority selector based on the starting bit location. The methods and structures then output, from the group selector to a multiplexor, the individual group priority bit of the selected round robin priority selector. Following this the method outputs, from the multiplexor, an output vector having a first value (e.g., 1) only in the individual group priority bit output by the group selector.
