A method, data processing system, and computer program product are provided for retrieving access rules using a plurality of subtables. An incoming packet that includes fields of data is received from a network. A key is formed from the fields, the key includes a number of subkeys. The subkeys are selected and each of the selected subkeys is used to search a different subtable. If a subtable entry is a pointer, a next level subtable is searched until a failure or data is encountered. If a failure occurs, a default rule is applied. If data is encountered, the key is masked using a stored mask value. The resulting masked key is compared to a stored rule. If they match, the identified rule is applied, otherwise the default rule is applied.

System and method for implementing ACLs using standard LPM engine

A method of and data processing system for determining whether a received signal in a Code Division Multiple Access system that uses an antenna array includes a desired signal with a predetermined timing offset, the method including correlatingthe received signal with a spreading code having the predetermined timing offset and corresponding to the desired signal at each element of the antenna array to provide correlations; determininga power distribution, such as a DFT, corresponding to the correlations that is a function of a direction of arrival of the received signal; comparinga magnitude of the power distribution at a first direction of arrival to a threshold that has a value that varies with the direction of arrival; and when the threshold is satisfied, determiningor indicating that the desired signal is likely present at the first direction of arrival.

Method and apparatus for determining whether a received signal includes a desired signal

An integrated circuit arranged and constructed to determine an upper data rate for a variable data rate signal and method thereof includes a buffer, comparator, and combiner that are operable to compare a characteristic, such as an energy statistic of a number of partial symbols constructed from the variable data rate signal to a first threshold that corresponds to the number to provide a first comparison; process the variable data rate signal at a first data rate when the first comparison is favorable; compare the characteristic to a second threshold that corresponds to the number to provide a second comparison; and combine the partial symbols to provide other partial symbols at a second data rate that is less than the first data rate when the second comparison is favorable.
