Patent number: 9304944Abstract: A memory access circuit and a corresponding method are provided. The memory access circuit includes a crypto block in communication with a memory that encrypts data of a data block on a block basis. The memory access circuit also includes a fault injection block configured to inject faults to the data in the data block. The memory access circuit further includes a data scrambler and an address scrambler. The data scrambler is configured to scramble data in the memory by shuffling data bits within the data block in a plurality of rounds and mash the shuffled data bits with random data. The address scrambler is configured to distribute the scrambled data across the memory. A memory system including the memory access circuit is also disclosed to implement the corresponding method.Type: GrantFiled: March 29, 2012Date of Patent: April 5, 2016Assignee: Broadcom CorporationInventors: Fong Pong, Eric Spada, Karen Schramm

Publication number: 20150131447Abstract: A method and system for network offloading includes receiving a packet at a communication interface of a wireless access point and processing the packet at a flow acceleration processor prior to processing the packet at a host processor. The flow acceleration processor may process the packet for header checking or security processing. The flow acceleration processor may provide the packet to a security coprocessor for security processing. The flow acceleration processor may generate a result code indicating whether the processing at the flow acceleration processor was successful. If the processing was unsuccessful, the packet is provided to the host processor for exception processing.Type: ApplicationFiled: January 20, 2015Publication date: May 14, 2015Inventors: Brian Petry, Eric Spada, Stephen Anderson, Scott Winterble

Patent number: 8929210Abstract: A system and method for enabling energy efficient Ethernet networks with time-sensitive protocols. Time-stamped packets generated by a time-sensitive protocol rely on fixed latency in a transit time through a transmission subsystem. An energy efficiency control policy in a network device governs a transmission of time-stamped packets in accordance with energy efficiency initiatives controlled by the energy efficiency control policy. In one embodiment, time-stamped packets can be dropped or modified to account for transitions by the transmission subsystem into an energy saving state. In another embodiment, transitions by the transmission subsystem into or out of an energy saving state can be impacted by the existence of time-stamped packets scheduled for transmission.Type: GrantFiled: December 12, 2013Date of Patent: January 6, 2015Assignee: Broadcom CorporationInventors: Wael William Diab, Eric Spada
