摘要： A network system by the present invention can quickly detect viruses and does not easily become a new cause of vulnerability. A packet data comparator branches inputted packet data into three branches, and includes an additional pattern matching unit which compares the branched data with the stored data and performs matching with collation patterns stored in a rewritable storage area, a fixed pattern matching unit which compares the branched data with the stored data and performs the matching with a logical operation configured with known collation patterns, a notification packet matching unit which compares the branched data with the stored data and finds a notification packet, and an identity detection aggregation unit which aggregates results from the respective matching units. Moreover, a virus filter, a virus checker, and a secure network system are realized by using the present invention.

摘要： Delay time between an input of data to a circuit block and an output of the data from the data block is measured in accordance with a timing at which the data from the circuit block is acquired by a measurement register and a timing at which the data from the circuit block is acquired by a data latch. An LSI tester sets well voltage adjustment values so that delay time of each circuit block is averaged. From voltages generated by the adjustment voltage generating circuit, a selector selects voltages that are in accordance with the well voltage adjustment values. The voltages selected are applied to a well of a CMOS transistor of each clock timing adjustment circuit. Delay time between timings of inputted clocks is thus adjusted.
