An interface unit 20 assigns different SDRAMs 1 and 2 to adjacent drawing blocks in a frame-buffer area. In processing that extends across the adjacent drawing blocks, active commands, for example, are issued alternately to the SDRAMs 1 and 2 to reduce waiting cycles resulting from the issue interval restriction. Furthermore, since individual clock enable signals CKE1 and CKE2 are output to the SDRAMs 1 and 2 so that burst transfers of the SDRAMs 1 and 2 can be stopped individually, no cycle is necessary to stop the burst transfers.

A terrestrial digital video broadcasting (DVB-T) network is used to transmit IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram sections and forward error correction (FEC) datagram sections are transmitted in separate time-sliced bursts using transport stream packets with different packet identifiers (PIDs).

A beam allocation method of a Base Station (BS) in a wireless communication system is provided. The method includes transmitting a reference signal to a Mobile Station (MS) using a plurality of downlink transmit (Tx) beams, receiving information of a plurality of candidate downlink Tx beams determined by the MS in response to the received reference signal, selecting at least one downlink Tx beam from the plurality of candidate downlink Tx beams according to a predefined rule, generating control information for burst transmission, comprising the selected at least one downlink Tx beam information, transmitting the control information to the MS using the selected at least one downlink Tx beam, and transmitting a data burst based on Tx beam information included in the control information.

A multi-mode transmitter architecture is configurable for multiple modulation modes using either polar or polar-lite modulation. Multiplexed signal paths and reconfigurable components are controlled for performance in GMSK and EDGE burst modes. Polar-lite EDGE modulation is programmed by setting a multiplexer coupling a first amplitude modulated signal path with a frequency modulated signal path input to a dual-mode power amplifier for amplification of the combined EDGE transmission signal. In full-polar EDGE modulation, amplitude modulated signal is multiplexed into a second amplitude modulated signal path for A / D conversion and comparison with a polar feedback signal coupled from the power amplifier output. The resulting comparison is applied to a power control port of the power amplifier to amplitude modulate the EDGE transmission output. Multiplexers are configured to disconnect the amplitude modulated paths when operating in GMSK signaling for both full-polar and polar-lite modulation. Multiplexers selectively couple power feedback into the second amplitude modulated signal path to provide power control and output power ramping for burst transmissions.

A stackable network unit which can form a ring with other units has a master mode in which it can place packets on the ring, so that they can be ultimately forwarded from other units, and a repeat mode in which it can make a request for transfer of mastership of the ring, inserting bits in a header of an arbitration packet. If a master unit has completed the transmission of a packet and, preferably, after the required inter-packet gap has elapsed, it has not yet received an arbitration header to permit the making of an arbitration decision it can transmit a subsequent packet. The header information of this packet indicates to the other units that this subsequent packet is part of a burst of packets and the other units should not set requests in the header of this packet because this packet would not be used for arbitration. The master unit indicates the nature of the subsequent packet by setting a sequence number in the header of the packet to distinguish it and following packets in a burst from the 'first' packet which is the one used to pick up requests from the units that may need to become the master unit.

In a multiprocessor system, comprising master and slave processors, a cache coherency controller, and address concentration devices; a method for improving coherent data transfers is described. A command transaction is generated, and a subsequent command from an initiator. Tags added to the responses or further request responses, stream on high-speed busses. Snoops and accumulated snoops expand on cacheline requests as each processor separates burst commands into multiple cacheline requests. Address concentrators containing a cacheline queue function, funnel transaction requests to a global serialization device, where a queuing process prioritizes indicia and coordinates the results among the processors. The cache issues a single burst command for each affected line. System coherency, performance, and latency improvements occur. Additional support for burst transfers between coherent processors is provided.

A shared storage network system comprises at least one storage client and a plurality of storage servers, each providing a storage portion of the shared storage network system, each storage portion being divided into a plurality of sectors, each sector being divided into a plurality of blocks, a virtual block identifier being associated to each of the blocks such that the entirety of all of the virtual block identifiers of the blocks form a global block address space in which each of the virtual block identifiers is unique. The plurality of storage servers and the at least one storage client are grouped into a plurality of local area networks interconnected with preferred optical channels to form a global network. The at least one storage client is adapted to have read and / or write access to at least one block of at least one of the storage portions associated to one of the local area networks which differs from the local area network of the storage client. The plurality of local area networks are interconnected such that in case of a read or a write access of one of the at least one storage client to at least one of the blocks, the virtual block address of a block to which access is desired is translated into a physical block address to identify the physical block associated with the virtual block. The shared storage network system is further adapted to implement a storage data transmission scheme comprising an optical burst mode flow control and an optical stop-over burst transmission method.
