Provided is a communication apparatus for direct communication between networks of different types. The communication apparatus includes a transmission data selector determining whether or not data input from a first communication network is speech data, a data processor digitizing and packetizing the data transferred from the transmission data selector, and a modem for converting the digitized and packetized data into analog data and then directly transmitting the analog data to a second communication network different from the first communication network through a speech channel.

Embodiments relate to view caching techniques that cache for a limited time, some of the (intermediate) results of a previous query execution, in order to avoid expensive re-computation of query results. Particular embodiments may utilize a cache manager to determine whether information relevant to a subsequent user request can be satisfied by an existing cache instance or view, or whether creation of an additional cache instance is appropriate. At design time, cache defining columns of a view are defined, with user input parameters automatically being cache defining. Cache instances are created for each tuple of literals for the cache defining columns, and for each explicit or implicit group by clause. Certain embodiments may feature enhanced reuse between cache instances, in order to limit memory footprint. Over time a cache instances may be evicted from memory based upon implementation of a policy such as a Least Recently Used (LRU) strategy.

A system includes determination of a total target value associated with N dimension members, determination of a set of historical values for each of the N dimension members, for each of the N dimension members, determination of a prediction interval based on the set of historical values of the dimension member, determination of an N-polytope in N-dimensional space based on the N determined prediction intervals, determination of an (N−1)-polytope of the N-dimensional space in which the sum of the N values of each coordinate of the (N−1)-polytope equals the total desired value, determination of an (N−1)-dimensional intersection of the N-polytope and the (N−1) polytope, and determination of a disaggregation of the total target value among the N dimension members based on the coordinates of the (N−1)-dimensional intersection.
摘要:
A buffer memory includes a memory cell array, a flag cell array, and a error correction block. The memory cell array has a plurality of word lines. Each of the plurality of word lines are electrically connected to a plurality of memory cells storing data. The flag cell array has a plurality of flag cells. Each of the plurality of flag cells is connected to each of the word lines and stores information that indicates whether error correction of the data has been performed. The error correction block performs error correction on the data output from the memory cell array in response to a command received through a host interface and flag data output from the flag cell array.
