<p>PROBLEM TO BE SOLVED: To obtain a data coincidence detector capable of minimizing size of a condition storage means by efficiently storing pieces of conditional data with various kinds of size in a condition storage means, performing a comparison processing between a condition and inputted data at high speed when the size of the conditional data is small and the number of conditions is less, setting many conditions when the number of conditions is less,. SOLUTION: A header coincidence detecting circuit 33a with a data holding circuit 41, data selecting circuits 421 to 424, comparative operation circuits 431 to 434, a coincidence judging circuit 45, a conditional memory 44 is used for a section data sorting circuit 25 in a transport packet processing circuit 21 as the data coincidence detector.</p> |
