An memory module including parallel data compression and decompression engines for improved performance. The memory module includes MemoryF / X Technology. To improve latency and reduce performance degradations normally associated with compression and decompression techniques, the MemoryF / X Technology encompasses multiple novel techniques such as: 1) parallel lossless compression / decompression; 2) selectable compression modes such as lossless, lossy or no compression; 3) priority compression mode; 4) data cache techniques; 5) variable compression block sizes; 6) compression reordering; and 7) unique address translation, attribute, and address caches. The parallel compression and decompression algorithm allows high-speed parallel compression and high-speed parallel decompression operation. The memory module-integrated data compression and decompression capabilities remove system bottlenecks and increase performance. This allows lower cost systems due to smaller data storage, reduced bandwidth requirements, reduced power and noise.

Roughly described, a packet switching fabric contains a separate queue scheduler for each combination of an input module and a fabric output port. The schedulers may also be specific to a single class of service. Each queue scheduler schedules its packets without regard to state of other input queues and without regard to packets destined for other output ports. In an aspect, the fabric manages per-flow bandwidth utilization of output port bandwidth capacity by monitoring the same and asserting backpressure toward the queue scheduler for any thread that is exceeding its bandwidth allocation. In another aspect, a switching fabric uses leaky buckets to apply backpressure in response to overutilization of downstream port capacity by particular subflows. In another aspect, a switching fabric includes a cascaded backpressure scheme.

Intercell handover method in UMTS mobile systems in TDMA-SCDMA technique (and also FDMS-SDMA) with full duplexing of the TDD type. The complexity of the technique adopted requires a frame synchronization mechanism employing a downlink pilot signal, broadcasting transmitted by the base station, echoed by signature sequences transmitted by the single Mobile units in the procedures foreseeing an uplink access.

An e-mail system is described that includes a mass-mail accelerator (MMA), which is particularly suited for processing mass e-mailings. Instead of being posted to a message transfer agent (MTA), outgoing messages are instead passed to the MMA for carrying out highly parallel e-mail delivery / routing. The MMA employs a plurality of queues, which may either be general or specific. A specific queue is configured to handle only e-mail destined for a particular domain, such as the AOL.com domain; a general queue is configured to handle all other e-mail. Each queue manages a pool of MTA threads. During MMA operation, once a message has been passed to a queue, that queue examines its MTA threads to see if one is ready to accept the message. If an MTA thread is ready, the queue will assign the message to that MTA. The MTA thread proceeds to handle the work of the SMTP exchange between the MMA and the target real-world MTA (e.g., an AOL MTA). While a given MTA thread is waiting for a reply from the real-world (destination) MTA (e.g., the AOL MTA), the MMA can proceed to do other work. In this manner, the bottleneck usually encountered with processing mass e-mailings is removed.
