Abstract
Methods of arbitrating between requestors and a shared resource are described. The method comprises generating a vector with one bit per requestor, each initially set to one. Based on a plurality of select signals (one per decision node in a first layer of a binary decision tree, where each select signal is configured to be used by the corresponding decision node to select one of two child nodes), bits in the vector corresponding to non-selected requestors are set to zero. The method is repeated for each subsequent layer in the binary decision tree, based on the select signals for the decision nodes in those layers. The resulting vector is a priority vector in which only a single bit has a value of one. Access to the shared resource is granted, for a current processing cycle, to the requestor corresponding to the bit having a value of one.
