Data sorting device having multi-input comparator comparing data input from latch register and key value storage devices

摘要

A data storage device for storing input data strings includes a comparator having (K+1) input ports for inputting K continuous sets of comparison data (K is an integer and at least 2) of the data strings for comparing data from K ports; and a controller for selecting the input port input to the comparator. A sort processor of the present invention provides a high performance sorting process and a high density sort processor in a semiconductor integrated circuit.
