Semiconductor memory asynchronous pipeline
An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage. The asynchronous control signals are generated within the chip and are optimized to the different latency stages. Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it.

The set of femto APs can be selected based at least in part on various criteria which can ensure that operation of the selected set of femto APs is a statistically meaningful representation of operation of the larger set of femto APs. Composite alarm thresholds facilitate triggering alarm(s) when a predetermined portion of the aggregated data reveal a BLER failure condition. Composite thresholds can be generated through analysis of aggregated uplink/downlink (UL/DL) BLER data for a set of femto APs.
Channel quality indicator transmission timing with discontinuous reception
A user equipment (UE) is disclosed. The UE includes a processor configured to begin channel quality indicator (CQI) transmissions using an assigned periodic CQI reporting resource before the start of the on-duration of a discontinuous reception (DRX) operation mode.
Reliability estimation methods for large networked systems
A computer-based method for determining a probability that no path exists from a specified starting node to a specified target node within a network of nodes and directional links between pairs of nodes is described. The nodes and directional links form paths of a reliability graph and the method is performed using a computer coupled to a database that includes data relating to the nodes and the directional links The method includes selecting a set of paths, from the set of all paths, between the starting node and the target node that have been determined to be reliable, calculating a reliability of the union of the selected path sets, setting an upper bound for the unreliability of the set of all paths, based on the calculated reliability, selecting a set of minimal cutsets from all such cutsets that lie between the starting node and the target node, calculating the probability of the union of the minimal cutsets, and setting a lower bound for the unreliability of the set of all cutsets.
United route query method in the automatic switched optical network
A joint route query method in ASON. After the route controller in each route domain has received a route query request, it calls a routing algorithm based on the request and the route calculation is performed based on the route database of the current node; if the route calculation succeeds, a route query result is returned to the requester, if no complete route can be obtained, said route query request will be forwarded to the RC in the parent domain. Based on the request, the RC in the parent domain interacts with RCs in other domain of the same layer, and the RCs in the sub-domains contained in the parent domain to complete the route query, and calculates to obtain a complete route, then a route query result will be returned to the RC that initiates the request and this RC will return the route query result to the requester.
Backward congestion notification
In one embodiment, an apparatus comprises a network interface system having at least one input port configured for receiving frames and a logic system comprising at least one logic device. The logic system may be configured to perform the following functions: determining a source address and a destination address of a frame received at an ingress port; calculating a flow hash based at least upon the source address and the destination address; forming a congestion management (“CM”) tag that includes the flow hash; inserting the CM tag in the frame; and forwarding the frame to the destination address.
