Patent number: 9372812Abstract: Embodiments of systems, apparatuses, and methods for determining if an instruction of a virtual machine is allowed to modify a protected memory region are described. In some embodiments, a system detects an indication of an attempt by the instruction to write to the protected memory region. In addition, the system determines if the instruction is allowed to write to the protected memory region based on a starting address and data length of the instruction. Furthermore, if the instruction is allowed to write to the protected memory region, the system updates the protected memory region with the instruction results.Type: GrantFiled: December 22, 2011Date of Patent: June 21, 2016Assignee: Intel CorporationInventors: Kuo-Lang Tseng, Baohong Liu, Ritu Sood, Manohar Ruben Castelino, Madhukar Tallam

Patent number: 8842790Abstract: Methods and systems to synchronize to a remote node counting rate, symbol rate, and carrier frequency as functions of an estimated frequency offset and relationships between the remote node carrier frequency and counting rate, and between the remote node carrier frequency and symbol rate. The carrier frequency offset may be scaled in accordance with a ratio between the carrier frequency and the remote counting rate to synchronize the local counting rate with the remote counting rate, and/or scaled in accordance with a relationship between the carrier frequency and the remote symbol rate to synchronize the local receive path and/or transmit path sample rate with the remote symbol rate. The carrier frequency offset may be applied as compensation in the receive path and/or the transmit path. The remote and local nodes may correspond to a network coordinator and an existing node, respectively, in a Multimedia Over Coax (MoCA) environment.Type: GrantFiled: December 22, 2009Date of Patent: September 23, 2014Assignee: Intel CorporationInventors: Kennan Laudel, Baohong Liu, Sowmiya Narasimhan, Sigang Qiu, Yongfang Guo

Patent number: 8719546Abstract: Embodiments of techniques and systems for using substitute virtualized-memory page tables are described. In embodiments, a virtual machine monitor (VMM) may determine that a virtualized memory access to be performed by an instruction executing on a guest software virtual machine is not allowed in accordance with a current virtualized-memory page table (VMPT). The VMM may select a substitute VMPT that permits the virtualized memory access, In scenarios where a data access length for the instruction is known, the substitute VMPT may include full execute, read, and write permissions for the entire guest software address space. In scenarios where a data access length for the instruction is not known, the substitute VMPT may include less than full execute, read, and write permissions for the entire guest software address space, and may be modified to allow the requested virtualized memory access. Other embodiments may be described and claimed.Type: GrantFiled: January 4, 2013Date of Patent: May 6, 2014Assignee: Intel CorporationInventors: Baohong Liu, Manohar R.

Patent number: 6731444Abstract: An apparatus and method for writing a product information code (PIC) to a head-disc assembly (HDA) of a disc drive data handling system to facilitate subsequent identification of the HDA. The PIC is configured as a sequence of n multi-bit encoded words. Servo data are written to a disc of the HDA as a number of p angularly spaced apart servo data fields, the servo data used by a servo control circuit to effect head positional control. The n encoded words are distributed across a subset n of the p servo data fields so that the n encoded words replace at least a portion of the servo data in the n servo data fields. Preferably, the n encoded words are written to Gray code (track address) fields of the n servo data fields and are provided with error detection and correction capabilities.Type: GrantFiled: June 1, 2001Date of Patent: May 4, 2004Assignee: Seagate Technology LLCInventors: JackMing Teng, BaoHong Liu, KianKeong Ooi, WingKong Chiang, Mingzhong Ding, BengWee Quak, Djunaedy Chandra Ang
