Granted: 2002-12-31
Abstract: A method of processing geophysical data on a parallel processor involves decomposition of an analysis cube into depth slices, a second decomposition of a data acquisition cube into traveltime slices, and determination of a variably dimensioned analysis aperture. Precomputed traveltimes are stored i n packed format to minimize storage volume and data bandwidths. A processing simulation is performed to optimize the stored sequence of the seismic trace  data and to minimize traveltime input/output demands. The method preferably assigns input/output, analysis, or control tasks to each processor, with dep th and traveltime slices assigned to each analysis processor. The method relies  on staged access of traveltime fields from high speed mass storage (104) to disk storage (108) and via the input/output processors (100) to analysis processor memory. Seismic trace data are also staged, preferably from tape storage to disk storage to processor memory, and preferably are broadcast under the control of a host computer. The method allows multiple common offsets to be simultaneously processed, and can be carried out on any type o f parallel processing computer.

In a preferred embodiment, the memory array provides wordlines which are accessible through column drivers (52). Each row or wordline is divided into a plurality of sector wordlines by inserting select transistors in the array. Each sector is driven by a column driver (52). In the read and programming modes, the sector wordlines are isolated from each other and are provided to the column drivers (52) through additional select transistors.  Only one memory cell from each sector wordline is read or programmed at a given time. In the erase mode, all sectors of a wordline are connected together through the select transistors, so that the erase operation may be accomplished for a complete row at a given time.

Title: Receiving portion of radio communication device
Inventor: ASANO NOBUO
IPC: H04B1/16
Filed: 1997-11-04
Granted: 2001-09-04
Abstract: A receiving portion of a radio communication device includes a circuit periodically moving into a sleep mode of operation. The circuit periodically moves out of the sleep mode of operation in response to a re-activation signal. A first clock signal is generated. Clock pulses in the first clock signal are counted. The re-activation signal is generated each time the number of the counted clock pulses in the first clock signal reaches an updatable number. A second clock signal is generated which has a frequency higher than a frequency of the first clock signal. Clock pulses in the second clock signal are counted during every time interval determined by the first clock signal. An error of the frequency of the first clock signal with respect to the frequency of the second clock signal is calculated on the basis of a result of the counting of clock pulses in the second clock signal. The updatable number is set in response to the calculated error of the frequency of the first clock signal.
