Abstract

PURPOSE: To avoid the increase in the number of comparators even if the number of keys in the cross reference table entry is increased, by constituting the conversion circuit with the Hash circuit converting the given key value into the number in a limited range and with a plurality of table memories storing the cross reference table having the value corresponding to the key value.
CONSTITUTION: The table memory 22 is split into a plurality of blocks, the key value given via the line 101 from external is converted into the entry address to the memory 22 with the Hash circuit 11 and it is outputted from the switch 29 by using the line 202. The switch 29 selects the entry for one block of the memory 22 via the line 203, the "key value" is given to one of the comparators 13 to 16 with the lines 111 to 114 and the "value" is outputted to the selector 18 via the lines 121 to 124. Thus, the comparators 13 to 16 compare the key value from external and obtain agreement/disagreement signal, and feeds it to the judgement unit 27 through the lines 131 to 134. After that, this operation is repeated and the value corresponding is fed to external.
