摘要:
Provided is a method of processing a packet for improving performance of an Ethernet switch. According to the present invention, a routine of searching a virtual local area network (VLAN) table by a decapsulation microblock and a bridge microblock may be performed by a core component when a core component generates tables and thus the number of memory accesses may be reduced. Also, VLAN port state information of an input port and VLAN port tagging information of an output port may be stored in metadata and may be transmitted to a next microblock. Accordingly, a duplicate memory access routine of the bridge microblock and an encapsulation microblock may be removed and thus an access time delay may be reduced, thereby improving performance of an Ethernet switch.

A stereoscopic image display and a method for driving the same are disclosed. The stereoscopic image display includes a display panel displaying a two-dimensional (2D) image data in a 2D mode and displaying a three-dimensional (3D) image data in a 3D mode, a gamma reference voltage generating circuit that generates first gamma reference voltages and second gamma reference voltages different from the first gamma reference voltages, outputs the first gamma reference voltages in the 2D mode, and outputs the second gamma reference voltages in the 3D mode, and data driver that converts the 2D image data into the first gamma reference voltages in the 2D mode and converts left eye image data and right eye image data into the second gamma reference voltages in the 3D mode.
摘要:
The present invention relates to a method and apparatus for transceiving data. A method in which a transmitting terminal transmits data to a receiving terminal in a MIMO system according to one embodiment of the present invention comprises the following steps: generating a data field containing the data; generating a signal field containing information on the data field; generating a data frame containing the data field and the signal field; and transmitting the data frame to the receiving terminal. According to the present invention, an end of the frame being transmitted is accurately notified to the receiving terminal in a communication system in which the frame is transmitted using MIMO, thereby decoding the frame in a more efficient manner at the receiving terminal.
