Patent number: 10523405Abstract: Link speed negotiation for 64 Gbps is done at 32 Gbps to allow only two speeds to be used during link state negotiation. The desire for 64 Gbps operation is indicated in a field shared during link state negotiation. After link speed negotiation is completed at 32 Gbps, a determination is made whether 32 or 64 Gbps operation is desired. If 32 Gbps operation is desired, procedures continue as in the prior operations. If 64 Gbps operation is desired, a new procedure is performed. The new procedure provides time for the optical transceiver to changeover from the PAM2 (pulse amplitude modulation) or binary operation used in 32 Gbps operation to the PAM4 multi-level operation used in 64 Gbps operation. After determining that the optical transceiver is ready to transmit, transmitter training is performed, with increased handshaking to provide improved granularity. After transmitter training is complete, conventional link initialization is performed.Type: GrantFiled: July 26, 2017Date of Patent: December 31, 2019Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE.

The method comprises: configuring a source mapping data structure to comprise an entry indicative of mapping between logical addresses corresponding to source data portion and addresses corresponding to source data portion and related to a physical address space; and, responsive to a move command, providing an atomic operation comprising configuring a destination mapping data structure to comprise an entry associated with said at least one destination range and comprising a reference to said entry in the source mapping data structure; and configuring said at least one entry in the source mapping data structure DSsrc to bear an indication that said one or more contiguous ranges of addresses corresponding to said source data portion in the source logical volume Vsrc are unavailable to a client.Type: GrantFiled: September 4, 2012Date of Patent: December 29, 2015Assignee: INFINIDAT LTD.Inventors: Ido Ben-Tsion, Leo Corry, Kariel Sandler, Jacob Broido

Patent number: 9225343Abstract: An electronics device is disclosed that reduces latency resulting from communication between a first electronics component operating based on a fast clock and a second electronics component operating based on a slow clock reduces communication latency. When transferring the data from the first component to the second, the data is written into a buffer using the first clock, and then extracted by the second component using the second clock. Alternatively, when transferring the data from the second component to the first component, the first component reads the data from the second component and monitors whether the data was extracted during a relevant edge of the second clock signal, in which case the first component again extracts the data from the second component.Type: GrantFiled: December 27, 2011Date of Patent: December 29, 2015Assignee: Broadcom CorporationInventors: Love Kothari, Mark Fullerton, Rajesh Rajan, Veronica Alarcon

Patent number: 9154417Abstract: A method and apparatus providing uninterrupted transmission of IP transmissions, during endpoint changes is disclosed. If a destination identifier in a received IP transmission matches a caller identifier of a record and a source address identifier or source identifier in the transmission do not match a caller address identifier or the caller identifier of the record, and a session identifier in the transmission matches a caller session identifier in the record, the source address identifier and the source identifier in the transmission are set as the caller address identifier and caller identifier respectively of the record. A similar procedure is followed to set the callee address identifier and callee identifier of the record using similar fields associated with the callee.Type: GrantFiled: November 27, 2013Date of Patent: October 6, 2015Assignee: DIGIFONICA (INTERNATIONAL) LIMITEDInventors: Pentti Kalevi Huttunen, Gavin Malcolm McMillan

Patent number: 9148126Abstract: An apparatus for sub-band processing of an input signal includes an analysis filter bank, signal processors and a synthesis filter bank. The analysis filter bank includes first and second signal branches for decomposing the input signal into two sub-band signals. The first signal branch includes a decimation filter connected upstream of a down-sampling unit and a basis filter. The second branch includes an all-pass filter and a subtractor that is connected downstream of the all-pass filter and the basis filter in the first signal branch via an up-sampling unit and a subsequent interpolation filter. At least one of the decimation filter and the interpolation filter is an infinite impulse response filter, and the all-pass filter has a phase response that compensates for a phase response of at least one of the decimation filter and the interpolation filter.Type: GrantFiled: December 8, 2009Date of Patent: September 29, 2015Assignee: Harman Becker Automotive Systems GmbHInventor: Markus Christoph

Patent number: 9136983Abstract: Data is streamed from a transmitter to a receiver, wherein streaming is transferring data with an assumption that the receiver will begin using the data before it is all transmitted and received and the streamed data includes forward error correction (“FEC”) and the rates of data consumption can vary. The transmitter has an input rate and a transmit rate and the two rates can be different and can change. At the receiver, there is a reception rate (at which the receiver receives data) and a consumption rate (at which the receiver uses up data for its output). The transmitter transmits using a transmit rate higher than the consumption rate and the extra bandwidth is usable for FEC protection and buffering. In some embodiments, the excess rate varies over a transmission period.Type: GrantFiled: February 13, 2007Date of Patent: September 15, 2015Assignee: Digital Fountain, Inc.Inventors: Mark Watson, Michael G. Luby

Patent number: 9130851Abstract: A system and method for increasing input/output speeds in a network switch. A physical layer device is provided that includes a physical coding sublayer that insert data flow identifiers to data flows that are provided to a gearbox. In one embodiment, the gearbox is a 5 to 2 gearbox that can transport various combinations of 10G/40G data flows over a narrower interface to a second physical layer device having an inverse gearbox.Type: GrantFiled: November 8, 2013Date of Patent: September 8, 2015Assignee: BROADCOM CORPORATIONInventors: Ali Ghiasi, Velu Pillai, Sundar Chidambara

Patent number: RE46026Abstract: A digital broadcasting system and a method of processing data are disclosed. Herein, additional encoding is performed on mobile service data, which are then transmitted, thereby providing robustness in the processed mobile service data, so that the mobile service data can respond more strongly against fast and frequent channel changes. The method of processing data in a transmitting system includes receiving mobile service data, encapsulating the received mobile service data to a transport stream (TS) packet, and outputting the encapsulated mobile service data as a mobile service data packet, and multiplexing a main service data packet including main service data and the encapsulated mobile service data packet, thereby transmitting the multiplexed data packets to at least one transmitter located in a remote site.Type: GrantFiled: November 14, 2014Date of Patent: June 7, 2016Assignee: LG ELECTRONICS INC.Inventors: Byoung Gill Kim, In Hwan Choi, Jin Woo Kim, Jong Moon Kim, Won Gyu Song, Hyoung Gon Lee, Kook Yeon Kwak
