摘要： Methods and apparatus for uplink control channel detection. In an exemplary embodiment, a method includes generating Top-Q Channel Quality Indicator (CQI) candidates from information received over an uplink control channel, generating a CQI symbol for each of the Top-Q CQI candidates, and generating a CQI energy metric from the CQI symbols. If the uplink control channel is formatted in format 2, then performing operations of combining the CQI energy metric with a pilot energy metric to generate a combined metric and searching the combined metric to determine transmitted CQI bits. If the control channel is formatted in format 2a or format 2b, then performing operations of generating an acknowledgement (ACK) energy metric for ACK candidates, combining the CQI energy metric, the pilot energy metric, and the ACK energy metric to generate the combined metric, and searching the combined metric to determine transmitted CQI bits and ACK bits.

摘要： Methods and apparatus for adaptive power profiling in a baseband processing system. In an exemplary embodiment, an apparatus includes one or more processing engines. Each processing engine performs at least one data processing function. The apparatus also includes an adaptive power profile (APP) and a job manager that receives job requests for data processing. The job manager allocates the data processing associated with the job requests to the processing engines based on the adaptive power profile. The adaptive power profile identifies a first group of the processing engines to perform the data processing associated with the job requests, and identifies remaining processing engines to be set to a low power mode.

摘要： A data processing system includes a phantom queue for each of a plurality of output ports each associated with an output link for outputting data. The phantom queues receive/monitor traffic on the respective ports and/or the associated links such that the congestion or traffic volume on the output ports/links is able to be determined by a congestion mapper coupled with the phantom queues. Based on the determined congestion level on each of the ports/links, the congestion mapper selects one or more non or less congested ports/links as destination of one or more packets. A link selection logic element then processes the packets according to the selected path or multi-path thereby reducing congestion on the system.

摘要： A system, apparatus, and method are provided for adding, deleting, and modifying rules in one update from the perspective of an active search process for packet classification. While a search processor searches for one or more rules that match keys generated from received packets, there is a need to add, delete, or modify rules. By organizing a plurality incremental updates for adding, deleting, or modifying rules into a batch update, several operations for incorporating the incremental updates may be made more efficient by minimizing a number of updates required.

摘要： A testbench for testing a device under test (DUT), wherein the testbench has a verification environment including a reference model, a scoreboard and a customized agent for each interface that the DUT needs to receive input from and/or transmit output on. The testbench system is able to be generated by a testbench builder that automatically creates a scoreboard, a reference model, a dispatcher and generic agents including generic drivers, loopback ports, sequencers and/or generic monitors for each interface and then automatically customize the generic agents based on their corresponding interface such that the agents meet the requirements of the interface for the DUT.

摘要： A new approach is proposed to offload of link aggregation from a host to a HBA in SRIOV mode. The HBA first creates one or more link aggregation offload engines each having one or more physical ports and to establish a first link between a VM running on the host and one of the link aggregation offload engines for network data transmission with the VM. Once a data packet is received from the VM over the first link, the link aggregation offload engine chooses a first physical port based on its link aggregation method and establish a second link with the chosen first physical port to transmit the packet out of the HBA. If the second link fails, the link aggregation offload engine then chooses a second physical ports and establish a third link with the chosen second physical port to transmit the packet out of the HBA device instead.

摘要： Managing memory access requests to a cache system including one or more cache levels that are configured to store cache lines that correspond to memory blocks in a main memory includes: storing stream information identifying recognized streams that were recognized based on previously received memory access requests, where one or more of the recognized streams comprise strided streams that each have an associated strided prefetch result corresponding to a stride that is larger than or equal to a size of a single cache line; and determining whether or not a next cache line prefetch request corresponding to a particular memory access request will be made based at least in part on whether or not the particular memory access request matches a strided prefetch result for at least one strided stream, and a history of past next cache line prefetch requests.
