High density plasma chemical vapor deposition and etch back processes that can fill high aspect ratio (typically at least 5:1, for example 6:1), narrow width (typically sub 0.13 micron, for example 0.1 micron or less) gaps with significantly reduced incidence of voids or weak spots are provided. This deposition part of the process may involve the use of any suitable high density plasma chemical vapor deposition (HDP CVD) chemistry. The etch back part of the process involves an integrated multi-step (for example, two-step) procedure including an anisotropic dry etch followed by an isotropic dry etch. The all dry deposition and etch back process in a single tool increases throughput and reduces handling of wafers resulting in more efficient and higher quality gap fill operations.

RLC processing section 106 supplies packet data requested for retransmission from a mobile terminal and new packet data not requested for retransmission to buffer 107 corresponding to data amounts controlled in HS-DSCH/FP processing section 108. Buffer 107 temporarily stores the packet data requested for retransmission and the new packet data not requested for retransmission to output at predetermined timing. HS-DSCH/FP processing section 108 detects a receivable data amount of the mobile terminal using CQI, and controls RLC processing section 106 so that the amount of data stored of packet data in buffer 107 does not exceed the receivable data amount of the mobile terminal. It is thereby possible to decrease the number of retransmissions to improve the throughput, and prevent suspension of the communication and disconnection of the channel.

Embodiments are directed toward a method for Behavior-based Traffic Differentiation (BTD) that initially receives incoming packets and performs traffic classification to determine the protocol of the incoming packets. In addition, BTD performs bandwidth division/allocation to further support traffic classification amongst non-TCP traffic such as UDP and ICMP. For TCP traffic, the method for BTD determines whether a TCP connection has been established and performs at least one of rate limiting, waiting time reduction for half-open connections, and incrementing backlog queue size when the TCP connection has not been established. If the TCP connection has been established successfully, the method for BTD further includes proactive tests for traffic differentiation which identify normal traffic, which is admitted, and attack traffic, which is dropped.

A method, system and processor for increasing the instruction throughput in a processor executing longer latency instructions within the instruction pipeline. Logic associated with specific stages of the execution pipeline, responsible for executing the particular type of instructions, determines when at least a threshold number of the particular-type instructions is scheduled to be executed.

The cycle frequency of only the one or more functional stages are switched to the higher cycle frequency independent of the cycle frequency of the other functional stages in the processor pipeline. The logic also automatically switches the execution cycle frequency of the specific pipeline stages back from the second, higher cycle frequency to the first cycle frequency, when the number of scheduled first-type instructions has completed execution.

A novel protocol for an ad-hoc, peer-to-peer radio network that provides collision-free channel access with an emphasis on improving geographic reuse of the frequency spectrum. The protocol of the invention is executed on the reservation or control channel, and provides a method for allocating data transactions on the data channels. The system of the invention utilizes multiple parallel data channels that are coordinated by a single reservation channel. The transceiver of the system employs two modems to solve the channel reliability issues with multiple channel designs, where one is dedicated as a receive-only modem for gathering channel usage information on the reservation channel. High quality voice, video and data may be transmitted. The reservation channel implements a time division multiple access algorithm with dynamic slot allocation. In a distributed manner, nodes determine geographic reuse of slots based on channel quality extracted from the modem. Signal quality calculations are used to determine the likelihood of a slot reuse causing destructive interference within a node's neighborhood. Requests for slot usage are compared with the known traffic pattern and accepted or rejected by nodes within RF signal range based on the signal quality calculations.
