Abstract

PURPOSE: To make it possible to use the highest queue element even in lower devices of the data processing, by performing input control and shift control of queue elements by the output of a priority comparing means to position the highest-priority queue element in the output stage of the shift register.
CONSTITUTION: Plural registers to enter queue elements into shift register part (SR)3 are provided, and priority key (a) held in priority key holding part 3nb of last-stage register 3n and priority key (b) held in priority key holding part 1b of input register 1 are compared with each other by 4. For a>b, queue elements input to input register 1 are not input to SR3, and contents of register 3n are set to register 31 through multiplexer 2, and SR3 is shifted to the right by one step as the whole. For b>a, contents of input register 1 are set to register 31. As a result, the highest- priority queue element can be always positioned in the output stage of SR3.
