an access request prioritization and summary device for determining the current highest priority among n entities . the device includes a bitmap having n bit storage locations . each one of the n bit storage locations corresponds to one of the entities and is used to store a value which represents when the corresponding entity is available for prioritization . a plurality of combinational logic blocks are connected to the bitmap so that each one of the combinational logic blocks receives a preselected portion of the values stored in the n bit storage locations of the bitmap . each one of the combinational logic blocks has a token signal input and a token signal output . the token signal inputs and outputs are coupled together to form a series of token signal links between the combinational logic blocks . when certain preselected highest priority determination conditions occur within one of the combinational logic blocks , the combinational logic block generates a token signal which serves as the token signal to the respective succeeding combinational logic block . each combinational logic block is capable of receiving a token signal from the previous combinational logic block and is responsive to the input of a token signal to determine a current highest priority from the values which it received as input signals .
