PROBLEM TO BE SOLVED: To provide a packet filter apparatus and a packet filter method whereby data after filtering can be acquired without the need for a data processing side using received data to execute processing for data capturing in particular and without limiting a filtering object in particular. SOLUTION: A filtering LSI 114 compares received data 122 sequentially stored in an FIFO memory 123 with an abort pattern stored in a filtering setting register 132 and deletes data coincident with the abort pattern. A timing generating circuit 124 generates a clock timing receivable by a CPU at a post stage (not shown) and gives data read in this timing from the FIFO memory in the older order to the CPU. Thus, it is not required for the CPU to receive a notice denoting the arrival of required data and to carry out the processing for extracting required data. COPYRIGHT: (C)2006,JPO&NCIPI
