Title: Apparatus for transmitting data using asynchronous transfer mode switch fabric in multiprocessor communication system
Inventor: NA SEOUNG HYEOK
IPC: H04L12/28
Filed: 1998-12-28
Abstract: PURPOSE: An apparatus for transmitting data is provided to prevent reductions of data amounts capable of being transmitted in a multiprocessor communication system, and to prevent reductions of bandwidth utilized by input/output modules even when the input/output modules are increased, so that a master module can simultaneously multicast the data in the input/output modules. CONSTITUTION: A multiprocessor communication system is composed of one master module having many processors and many input/output modules. The master module in an apparatus for transmitting data between the processors in the multiprocessor communication system, comprises a processor(110), a cell divider/reassembler(120), a router(130), and an asynchronous transfer mode(ATM) switch fabric(140). The processor processes a packet for being transmitted/received. The cell divider/reassembler divides the packet for being transmitted into an ATM cell, and reassembles the received ATM cell. The cell divider/reassembler outputs the reassembled ATM cell to the processor as a restored packet. The router sets up a first switching path by attaching a tag to the ATM cell, and omits the tag of the received ATM cell. The router outputs the tag-omitted ATM cell to the cell divider/reassembler. The ATM switch fabric switches and copies the ATM cell according to the first switching path. The AMT switch fabric transmits the ATM cell to a corresponding input/output module of the many input/output modules. The ATM switch fabric receives the ATM cell from one of the input/output module, and outputs the ATM cell to the router according to a second switching path. Each of the input/output modules(301,302,303) comprises a router(330), a cell divider/reassembler(320), and a processor(310). The router receives the ATM cell transmitted from the master module to omit the tag, and attaches a tag to an ATM cell for being transmitted. The router transmits the ATM cell to the master module according to the second switching path. The cell divider/reassembler reassembles the ATM cell to output the reassembled ATM cell as a restored packet. The cell divider/reassembler divides a packet for being transmitted to output the packet to the router as an ATM cell. The processor outputs the packet for being transmitted to the cell divider/reassembler, and receives the restored packet to process the packet.

Abstract: PURPOSE: A driving method of PDP(Plazma Display Panel) using RF(Radio Frequency) discharge is provided to minimize image distortion caused by a different amount of light emission among each sub-field resulted from inhomogeneity of an amount of wall charges among address discharge periods in each sub-field. CONSTITUTION: A driving method of PDP using RF discharge is forming sequentially the first address discharge period(Ta1), the first sustain discharge period(Ts1), the second address discharge period(Ta2) and the second sustain discharge period(Ts2) in each sub-field(SF1,SF2,.....). Because an address discharge period(Ta1 or Ta2) is one half of a conventional address discharge period in one sub-field and RF discharge is conducted twice in each sub-field(SF1,SF2,.......), wall charges are uniformly accumulated within a discharge cell in the respective address periods(Ta1,Ta2) and minimum image distortion is achieved.
