Publication number: 20140117521Abstract: A lead frame for assembling a semiconductor device has a die pad surrounded by lead fingers. Each of the lead fingers has a proximal end close to but spaced from an edge of the die pad and a distal end farther from the die pad. A semiconductor die is attached to a surface of the die pad. The die has die bonding pads on its upper surface that are electrically connected to the proximal ends of the lead fingers with bond wires. An encapsulation material covers the bond wires, semiconductor die and the proximal ends of the lead fingers. Prior to assembly, hot spots of the die are determined and the lead fingers closest to the hot spots are selected to project closer to the die than the other lead fingers. These longer lead fingers assist in dissipating the heat at the die hot spot.Type: ApplicationFiled: October 29, 2012Publication date: May 1, 2014Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: Chetan Verma, Piyush Kumar Mishra, Cheong Chiang Ng

Patent number: 8306954Abstract: Methods and systems for efficient file replication are provided. In some embodiments, one or more coarse signatures for blocks in a base file are compared with those coarse signatures for blocks of a revised file, until a match is found. A fine signature is then generated for the matching block of the revised file and compared to a fine signature of the base file. Thus, fine signatures are not computed unless a coarse signature match has been found, thereby minimizing unneeded time-consuming fine signature calculations. Methods are also provided for determining whether to initiate a delta file generation algorithm, or whether to utilize a more efficient replication method, based upon system and/or file parameters. In accordance with additional embodiments, the lengths of valid data on physical blocks are obtained from physical block mappings for the files, and these lengths and mappings are utilized for delta file generation, to minimize unnecessary signature computations.Type: GrantFiled: November 22, 2010Date of Patent: November 6, 2012Assignee: Oracle International CorporationInventors: Piyush Kumar Srivastava, Madhusudhana Honnuduke Srinivasa Murthy

Publication number: 20090325533Abstract: Portable battery operated electronic devices often use a “sleep mode” for energy conservation. A key feature introduced in the IEEE 802 standard ensures power-efficient operation of these battery operated mobile devices. However, the standard fails to define what will trigger a device into the sleep mode while other systems define “waiting time threshold” as a time for which a Mobile Subscriber Station (MSS) waits before entering into sleep mode which has a constant duration. An embodiment of the present invention uses a unique method (1500) and algorithm for optimizing waiting time threshold (1509) according to traffic arrival pattern for uplink (UL) and downlink (DL) data packets. This leads to significant reduction in energy consumption with little increase in average waiting delay and acceptable end-to-end delay for non real time traffic.Type: ApplicationFiled: June 27, 2008Publication date: December 31, 2009Inventors: Abhijit Lele, Ramakrishnan R, Debabrata Das, Piyush Kumar Jain, Khyati Sanghvi
