Abstract: A method of routing a packet in a routing device having a main processor that includes a main cache table and an instant cache table is disclosed. The instant cache stores a recent address and a recent interface associated with the most recent packet transmission process made by the routing device. The method includes the steps of receiving a packet that includes its destination address, checking whether the destination address belongs to the routing device, checking whether the destination address is identical to the recent address if the destination address does not belong to the routing device, and transmitting the packet to the recent interface if the destination address is identical to the recent address. As a result, the core information related to the routing path determination is stored not only in the routing table of the protocol layer but also in the main and instant cache tables included in the main processor.

Abstract: An apparatus for inspecting a wafer includes a handling unit for supporting, rotating and moving the wafer in horizontal and vertical directions, a first image acquisition unit for acquiring a first image corresponding to an upper surface of the wafer supported by the handling unit, a second image acquisition unit for acquiring a second image, a third image and a fourth image corresponding to a peripheral portion of the upper surface, a side surface and a lower surface of the wafer supported by the handling unit, respectively, a first driving unit for rotating the second image acquisition unit about a peripheral portion of the wafer supported by the handling unit in order to acquiring the second, third and fourth images, and an image processing unit for inspecting defects of the wafer supported by the handling unit from the first to fourth images.

Abstract: An automatic beam limiter circuit (ABL circuit) calculating an average of a video signal at least a portion of the video signal is provided. After a converter circuit converts an analog signal, which is generated from the video signal, to a digital signal, a horizontal and a vertical average circuits calculate a horizontal and vertical averages of the digital signal at least a portion of the digital signal. The portion of the digital signal is a scanned line of the digital signal on a CRT. A comparison circuit compares a first calculation value calculated between a reference value and the vertical average with a second calculation value calculated between the reference value and the horizontal average, and outputs a first comparison signal and a second comparison signal based on the comparison results. A gain control circuit produces a gain control signal for adjusting the brightness/contrast in response to the first comparison and second comparison signals.

Abstract: An apparatus for detecting when an output load of a digital-to-analog converter is changed to another value, automatically sensing the converted output load, and supplying a stable current to the output terminal of the digital-to-analog converter. Normally a digital-to-analog converter operated for processing a digital video signal, has two kinds of output loads, 75.OMEGA. and 37.5.OMEGA.. The apparatus detects whether the output load of the digital analog converter is 75.OMEGA. or 37.5.OMEGA., varies output current according to the detected output load, and therefore actively adjusts the video output voltage to be constantly in the range of 1V.sub.P--P.
