Patent number: 7848570Abstract: To provide a memory efficient method and system for statistical data accumulation and processing, data is divided into multiple data zones and divided into subgroups of memories. A separate memory bin is assigned for each of the subgroups, and this memory bin is shared between various two data zones in each subgroup for processing and accumulation. In this scheme, the histogram data in each location of the separate memory bin for the previously accumulated data zones is processed before updating the stored value for the data zone requiring data accumulation.Type: GrantFiled: December 13, 2006Date of Patent: December 7, 2010Assignee: STMicroelectronics Pvt.

Patent number: 7197469Abstract: A method and system for resource rationing which employs decision rules for the optimal allocation of supply and capacity over time that satisfy two key requirements (a) being consistent with accepted operational objectives (e.g. low inventory, short lead times, prioritized allocation of supply and capacity) and (b) allowing for the timely computation of a feasible production schedule. The method and system is generally characterized in that it is able to divide each of the priority ranked scheduled releases (Material Requirements Planning (MRP)) into “N” separate and smaller sized scheduled releases where the priority of each of the “N” releases may be equal to the priority of the original release. The “N” separate and smaller sized scheduled releases are sorted according to priority and then used to determine an optimal supply schedule for allocating resources including component supply and assembly capacity.Type: GrantFiled: June 26, 2001Date of Patent: March 27, 2007Assignee: International Business Machines CorporationInventors: Sanjay R.

Patent number: 7164641Abstract: An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device.Type: GrantFiled: September 28, 2004Date of Patent: January 16, 2007Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kyosuke Yoshimoto, Mahesh Chandra Rao, Hiroyuki Ohata, Kazuhiko Nakane, Teruo Furukawa, Junichi Kondo, Masafumi Ototake

Patent number: 5930358Abstract: A storage device or drive such as a disk or tape drive including a nonvolatile erasable semiconductor memory which stores parameters which control the operation of the storage device. Through a user interface on a host computer, the user is capable of changing the parameters which are used to control the storage device, allowing the user to configure the operation of the storage device in any manner desired. The parameters which are changeable within the storage device relate to responses to the detection of errors within the storage device, data encryption algorithms, the stopping of a disk from spinning, the caching of the storage device, and data compression algorithms. The storage drive also has the capability to perform a stand-alone formatting operation. After formatting a storage medium with the assistance of the host computer, the formatted medium is read by the drive and stored in the nonvolatile memory of the storage drive.Type: GrantFiled: March 13, 1997Date of Patent: July 27, 1999Assignee: Mitsubishi Chemical America, Inc.Inventor: Mahesh Chandra Rao
