Patent number: 9426745Abstract: A filter expression is received at a wireless device assembly of a communication device. While a host assembly of the communication device is in a sleep mode, the wireless device assembly receives a signal having packet data, and determines whether the packet data contains a data pattern indicated by the filter expression. If the packet data contains the data pattern, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. If the packet data does not contain the data pattern, the wireless device assembly does not communicate the wakeup signal to the host assembly.Type: GrantFiled: November 9, 2015Date of Patent: August 23, 2016Assignee: MARVELL INTERNATIONAL LTD.Inventors: Long Chow, James Kang-Wuu Jan, Robert Lee, Chen Fan, Xiaohua Luo, Frank Huang

Patent number: 9326233Abstract: A host assembly of a wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.Type: GrantFiled: July 1, 2013Date of Patent: April 26, 2016Assignee: MARVEL INTERNATIONAL LTD.Inventors: Frank Huang, James Kang-Wuu Jan, Robert Lee, Sandesh Goel, Bing Zhao, Yao Chen, Chen Fan

Patent number: 9185653Abstract: In a method and apparatus for providing memory efficient filtering of a received broadcast signal, a wireless device assembly compares a filter expression to packet data in the broadcast signal to determine whether the packet data contains a particular bit pattern indicated by the filter expression. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. If the host assembly is in a sleep mode, and if the packet data contains the particular bit pattern indicated by the filter expression, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. On the other hand, if the packet data does not contain the particular bit pattern indicated by the filter expression, the wireless device assembly does not communicate the wakeup signal to the host assembly.Type: GrantFiled: March 17, 2014Date of Patent: November 10, 2015Assignee: MARVELL INTERNATIONAL LTD.Inventors: Long Chow, James Kang-Wuu Jan, Robert Lee, Chen Fan, Xiaohua Luo, Frank Huang

Patent number: 8675531Abstract: In a method and apparatus for providing memory efficient filtering of a received broadcast signal, filter expressions are compared to packet data in the broadcast signal and by a wireless device assembly to determine if a match exists. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. Upon finding a filter match, the wireless device assembly selectively communicates the received packet data to the host assembly for packet decoding and analysis. If the host assembly is in a sleep mode, the wireless device assembly may send a wakeup signal to the host assembly prior to transmitting the packet data.Type: GrantFiled: June 3, 2011Date of Patent: March 18, 2014Assignee: Marvell International Ltd.Inventors: Long Chow, James Kang-Wuu Jan, Robert Lee, Chen Fan, Xiaohua Luo, Frank Huang

Patent number: 8478364Abstract: A host assembly is communicatively coupled to a wireless device assembly via a first interface and via a second interface. A first signal is received at the wireless device assembly from the host assembly. The first signal indicates a request for the wireless device assembly to enter a host sleep mode of operation. In response to receiving the first signal, the wireless device assembly transmits a third signal to the host assembly, wherein the third signal indicates entry into the host sleep mode of operation. Subsequent to transmitting the third signal to the host assembly via the first interface, the wireless device assembly enters into the host sleep mode of operation. While in the host sleep mode of operation, the wireless device assembly transmits, via the second interface, the second signal, and, after transmitting the second signal to the host assembly, exits the host sleep mode of operation.Type: GrantFiled: April 30, 2012Date of Patent: July 2, 2013Assignee: Marvell International Ltd.Inventors: Frank Huang, James Kang-Wuu Jan, Robert Lee, Sandesh Goel, Bing Zhao, Yao Chen, Chen Fan
