A novel and useful cost effective mechanism for detecting the livelock/starvation of transactions in a ring shaped interconnect that utilizes minimal logic resources. Rather than monitor all transactions concurrently in the ring, the mechanism monitors only a single transaction in the ring. A sampling point is located at a point in the ring which contains a set of N latches. If the monitored transaction is not being starved, it is released and the detection logic moves on the next candidate transaction in round robin fashion. If the monitored transaction passes the sampling point a threshold number of times, it is deemed to be starved and a starvation prevention handling procedure is activated. By traversing the entire ring a single transaction at a time, all starving transactions will eventually be detected with an upper limit on the detection time of O(N2).

A propagation delay in the transmission of a frame from an initiator node to a peer node is determined by initially identifying a frame number and byte offset of a first incoming frame from the peer node at a time when the initiator node outputs a portion of a transmitted frame. The portion of the transmitted frame may be the first byte of a sub-frame within the transmitted frame. At the peer node, the frame number and byte offset of a second frame to be supplied to the initiator node is identified at a later time when the frame portion transmitted by the initiator node is received by the peer node, and such information is transmitted to the initiator node. Thus, since the frames output and received by the initiator node are typically of fixed duration, the frame number and byte offset of the incoming frame represent the time when the initiator node outputs the frame portion (a transmit time). In addition, the frame number and byte offset of the second frame represents the time at which the frame portion is received by the peer node (a receive time). Accordingly, by comparing the frame numbers and byte offsets of the first and second frames received from the peer node, a difference between transmit and receive times or propagation delay can be obtained.

Prefix length memory tables are used to enable fast IPv4 LPM lookups using a single memory access for a first range of IP prefixes, and using two memory accesses for larger IP prefixes. Each of the prefix length memory tables is used to hold a set of forwarding rules associated with a different prefix length range. IP LPM operations are then performed in parallel in each of the prefix length memory tables of the set, and the forwarding rule matching the longest prefix is returned from each of the memory tables. A priority encoder is used to select between positive results from the multiple prefix length memory tables to enable the forwarding rule with the largest matching prefix to be used to key into the next hop forwarding table. The method utilizes low cost DDR SDRAM rather than TCAM, and also exhibits low overhead.

Accordingly, handover processing time can also be reduced. In addition, time for switching the voice path is minimized, so that it is possible to considerably reduce a mute interval which inevitably occurs during a handover.

A base station supports a contention-based channel and a schedule-based channel. If too many mobile terminals simultaneously transmit on the contention-based channel, the base station schedules retransmissions to those terminals on the schedule-based channel. Supporting this, a terminal transmits a user transmission on the contention-based channel that includes both a data transmission and a reference signal. The terminal derives this reference signal by selecting one of a plurality of cyclic shifts (CSs). Correspondingly, the base station receives the user transmission and can determine the selected CS even if it is unable to demodulate the data transmission. The base station then determines a retransmission identifier (RTI) mapped to that CS, according to a mapping between CSs and RTIs, and sends scheduling information for any needed retransmission to the terminal by addressing that information to the RTI. Meanwhile, the terminal knows this mapping and monitors for scheduling information addressed to that RTI.

A system that includes a polyphase filter comprises first and second gm-C filters with first and second variable biasing and a bias controller coupled to the first and second gm-C filters and configured to offset the first variable biasing and corresponding first gm of the first gm-C filter relative to the second variable biasing and corresponding second gm of the second gm-C filter to thus improve image rejection in the system. A corresponding method includes processing a signal in a complex polyphase filter and controlling biasing of the first gm-C filter stage relative to the second gm-C filter stage to provide a mismatched gm and thereby improve rejection of the image signal.
