    摘要: A dipole acoustic well logging instrument including an acoustic transmitter. Receiver sections are disposed at axially spaced apart locations from the acoustic transmitter. Each receiver section includes an outer shoulder at each end adapted to be placed in acoustically isolated contact with an internal shoulder of a connector coupling when the instrument is in tension. The outer shoulders have an acoustically isolating material disposed on their surfaces. The receiver sections include an inner shoulder at each end adapted to be placed in direct contact with an external shoulder of the connector coupling when the instrument is in compression. The instrument includes one connector couplings disposed at each end of each receiver section to couple the receiver sections to each other and to the remainder of the instrument. At least one receiver element is disposed in a passage formed into each of the receiver sections. In one embodiment of the invention, the receiver element can be a bimorph-type dipole acoustic sensor. In another embodiment, the receiver element can be formed from a plurality of radially spaced apart piezoelectric elements.

    摘要: A computer system that includes a CPU, a memory and a memory controller for controlling access to the memory. The memory controller generally includes arbitration logic for deciding which memory request among one or more pending requests should win arbitration. When a request wins arbitration, the arbitration logic asserts a “won” signal corresponding to that memory request. The memory controller also includes synchronizing logic to synchronize memory requests, corresponding to a first group of requests, that win arbitration to a clock signal and an arbitration enable signal. The synchronizing logic includes an AND gate and a latch for synchronizing the won signals. The memory controller also asynchronously arbitrates a second group of memory requests by asserting a won signal associated with the second group requests that is not synchronized to the clock signal. In this manner, the won signals for the second group of requests can be asserted earlier than the synchronized won signals, thereby permitting the asynchronously arbitrated second group memory requests to be performed earlier than otherwise possible.

    摘要: In accordance with principles of the present invention methods and apparatus are provided for evaluating the quality of the cement bond in cased boreholes. Acoustic energy is used to excite the borehole-casing-annulus-formation system and the quality of the cement bond is determined by examining the ratios of the signals received by two longitudinally spaced apart receivers supported on a sonde. The acoustic energy is generated by two transmitters symmetrically disposed above and below the receivers along the sonde. The spacings between the receivers themselves and between the receivers and the transmitters are selected so as to enhance the correlation between the ratios of the received signals and the quality of the cement bond log. An additional receiver, supported on the sonde at a small distance from one of the transmitters, is employed to determine the quality of the cement bond in hard formations.

    摘要: Method and apparatus for improving processor performance. In some embodiments, processing speed may be improved by reusing data stored in a buffer during an initial request by subsequent requests. Assignment of temporary storage buffers in a controller may be made to allow for the potential for reuse of the data. Further, a hot buffer may be designated to allow for reuse of the data stored in the hot buffer. On subsequent requests, data stored in the hot buffer may be sent to a requesting device without re-retrieving the data from memory.

    摘要: A method of adding memory capacity to a computer system. The computer system comprises a redundant memory system including a plurality of memory cartridges. By powering-down a memory cartridge, adding an additional memory module to the memory cartridge, and powering-up the memory cartridge for each memory cartridge in the system, the system can transition from a redundant mode of operation to a non-redundant mode of operation for each power-down, thus allowing the computer system to remain functional during the addition of the memory module. Alternatively, memory cartridges with higher memory capacity than those currently present in the computer system can be used to replace existing memory cartridges in the computer system, using the same techniques.

    摘要: A computer is provided having a bus interface unit coupled between a CPU bus, a peripheral bus, and a memory bus. The bus interface unit includes a processor controller linked to the CPU bus for controlling the transfer of cycles from the CPU to the peripheral bus and memory bus. Those cycles can be arranged in order within the CPU bus pipeline. A subset of cycles destined for a peripheral bus can be stalled within a snoop phase associated with the CPU bus. Snoop stall can continue until a memory cycle is encountered upon the CPU bus pipeline within a phase prior to the snoop phase. Once the memory cycle progresses to the snoop phase, snoop stall can be discontinued and the previous, peripheral cycles can then be deferred and/or retried, allowing the memory cycle to be quickly dispatched through all phases of the CPU bus and onto the memory bus. In this fashion, memory cycles can be completed quickly, yet deferrals or retries are minimized to avoid the throughput penalty associated with deferring or retrying cycles back again through each phase of the CPU bus.
