Abstract: A Doherty amplifier is able to enhance efficiency in low-power and high-power RF communication states by enabling carrier and peaking amplifiers as required, and controlling bias modulation, depending on traffic loading levels in each of a set of consecutive communications timeslots. For example, if, in a low-power state, traffic loading levels do not exceed a relatively lower threshold in a communications timeslot, carrier amplifiers are selectively enabled as needed, peaking amplifiers are not enabled, and carrier amplifier bias levels are kept substantially constant. If, in an intermediate-power state, the lower threshold is exceeded but a relatively higher threshold is not exceeded, all carrier amplifiers are enabled, peaking amplifiers are selectively enabled, and bias levels are kept substantially constant. If, in a high-power state, the higher threshold is exceeded, all carrier and peaking amplifiers can be enabled, and the peaking amplifier bias tracks the RF envelope of the received RF signal.

Abstract: Methods and systems are disclosed to access memory locations using auxiliary keys in addition to primary keys. Commands are received by a memory management unit to insert or access records in an exact match keyed lookup table where records include keys (i.e., primary keys), auxiliary keys, and data. When a command to insert a new record is received along with key and data, the memory management unit generates a new unique auxiliary key. The auxiliary key includes a table index generated from the key and a collision index that is unique for any records having the same table index. The key, the auxiliary key, and the data for the new record are then stored within the lookup table along with a collision pointer that links records having the same table index. Subsequently, commands to access the new record can selectively use either the original key or the auxiliary key.
