Patent number: 9712442Abstract: A system for efficient memory bandwidth utilization may include a depacketizer, a packetizer, and a processor core. The depacketizer may generate header information items from received packets, where the header information items include sufficient information for the processor core to process the packets without accessing the payloads from off-chip memory. The depacketizer may accumulate multiple payloads and may write the multiple payloads to the off-chip memory in a single memory transaction when a threshold amount of the payloads have been accumulated. The processor core may receive the header information items and may generate a single descriptor for accessing multiple payloads corresponding to the header information items from the off-chip memory. The packetizer may generate a header for each payload based at least on on-chip information and without accessing off-chip memory. Thus, the subject system provides efficient memory bandwidth utilization, e.g.Type: GrantFiled: November 5, 2013Date of Patent: July 18, 2017Assignee: Broadcom CorporationInventors: David Wu, Darren Duane Neuman, Flaviu Dorin Turean, Rajesh Shankarrao Mamidwar, Anand Tongle, Predrag Kostic

Publication number: 20170187472Abstract: The present disclosure is directed to apparatuses for preventing significant amounts of common mode noise from a PHY transceiver, such as an Ethernet PHY transceiver, from coupling to an unshielded twisted-pair cable. The apparatuses can provide common mode noise isolation, while limiting any common mode noise to differential mode noise (CM-DM) conversion. Common mode noise is generally ignored by a PHY transceiver that receives a differential data signal because of differential signaling. However, when common mode noise is converted to differential mode noise, then data errors can result. Thus, limiting any CM-DM conversion is important.Type: ApplicationFiled: December 20, 2016Publication date: June 29, 2017Applicant: Broadcom CorporationInventors: Ahmad CHINI, Mehmet V. TAZEBAY

Patent number: 9674113Abstract: A data bridge controls packet transfers between network fabrics forming a closed network, such as a vehicular network and a home network. The data bridge includes two or more sets of modules, each of which communicates with a different network fabric. When a packet is to be delivered between network fabrics, a first set of modules, which is used to communicate with a first network fabric, decides whether to accept the packet or discard it. If the packet is accepted, it is delivered to a second set of modules, which is used for communicating with a second network fabric. The second set of modules makes a second, independent decision about whether the packet will be sent to the second network fabric. Each set of modules can base its decision on packet content type, and may discard any packet not to be delivered to the other network.Type: GrantFiled: May 11, 2015Date of Patent: June 6, 2017Assignee: BROADCOM CORPORATIONInventors: Nariman Yousefi, Yongbum Kim, John Walley, Sherman (Xuemin) Chen, Wael W.

Publication number: 20170150313Abstract: Wireless access points within a GPS-Unavailable environment can provide location services to user equipment devices within the environment provided that the access points are aware of their precise locations. In order to calibrate the locations of the wireless access points, a user equipment is moved to specific locations within the environment. At each of those locations, the user equipment transmits calibration signals that include the transmission location as well as a timestamp of the transmission time. Upon receipt by the access points, these signals are timestamped with a reception timestamp by a clock that is synchronized with the clock of the user equipment. After accumulating sufficient calibration information from a sufficient number of calibration locations, the access points can accurately determine their locations using trigonometric and other functions.Type: ApplicationFiled: December 31, 2015Publication date: May 25, 2017Applicant: Broadcom CorporationInventor: Nicholas Ilyadis
