    摘要: A memory controller which provides a series of queues between the processor and the PCI bus and the memory system. Memory coherency is maintained in two different ways. Before any read operations are accepted from the PCI bus, both of the posting queues must be empty. A content addressable memory (CAM) is utilized as the PCI to memory queue. When the processor performs a read request, the CAM is checked to determine if one of the pending write operations in the PCI to memory queue is to the same address as the read operation of the processor. If so, the read operation is not executed until the PCI memory queue is cleared of the write. To resolve the problem of aborting a Memory Read Multiple operation, an abort signal from the PCI bus interface is received and as soon thereafter as can be done the read ahead cycle is terminated, even though the read ahead cycle has not fully completed. The memory controller has improved prediction rules based on whether the cycle is coming from the processor or is coming from the PCI bus to allow more efficient precharging when PCI bus cycles are used. The memory controller is highly programmable for multiple speeds and types of processors and several speeds of memory devices. The memory controller includes a plurality of registers that specify number of clock periods for the particular portions of a conventional DRAM cycle which are used to control state machine operations.

    摘要: An arbiter circuit for controlling access to the main memory for requests asserted by the microprocessor, the refresh controller and PCI bus masters. Generally, the priority of the memory requests are as follows, with some exceptions: (1) second refresh request; (2) processor-to-memory write request; (3) memory-to-processor read request; (4) PCI-to-memory write request; (5) memory-to-PCI read request; and (6) first refresh request. The second refresh request indicates that two refreshes are outstanding. When that occurs, both outstanding refresh requests are assigned the highest priority. The processor-to-memory write request is always higher in priority than other memory requests except the second refresh. However, under certain conditions, the processor-to-memory write requests is held off to allow other cycles to proceed. The memory-to-processor read request is generally higher in priority than the PCI write and read requests, unless certain conditions occur to override that priority. PCI-to-memory write requests are always higher in priority than memory-to-PCI read requests.

    摘要: Systems and methods are presented that detect and classify mass-like regions exhibiting spiculated and/or dense characteristics with high sensitivity and at acceptable false positive rates. One or more suspicious masses are identified in medical imagery of the breast. In certain embodiments, a quantitative measure of spiculation and quantitative measure of density are computed for each suspicious mass located. At least one classification scheme, developed using true and false positives with similar quantitative measures, is then selected for each suspicious mass according to both quantitative measures. In certain other embodiments, a measure of breast location is computed for each suspicious mass. In one embodiment, the location determines whether a suspicious mass appears inside or outside of the parenchyma region of the breast.

    摘要: A structured prediction model learning apparatus, method, program, and recording medium maintain prediction performance with a smaller amount of memory. An auxiliary model is introduced by defining the auxiliary model parameter set θ(k) with a log-linear model. A set Θ of auxiliary model parameter sets which minimizes the Bregman divergence between the auxiliary model and a reference function indicating the degree of pseudo accuracy is estimated by using unsupervised data. A base-model parameter set λ which minimizes an empirical risk function defined beforehand is estimated by using supervised data and the set Θ of auxiliary model parameter sets.

    摘要: A hand-held power drill incorporates an electronic voltage sensor having a sensing input conductively connected to the drill chuck so that a drill bit held by the chuck serves as a voltage sensing element. The electronic voltage sensor can operate an audible or visible warning device, and can also disable the drill motor, when the drill bit is in close proximity to a live wire. A two pole switch with successively closed sets of contacts allows the drill to be used as a voltage probe without operating the drill motor. An auxiliary by-pass switch gives the operator the option to operate the drill even when it is in proximity to a live wire.
