    摘要： Techniques for dynamically managing receiver resources to achieve good latency and throughput performance are described. A receiver may have various types of receiver resources such as demod resources for demodulating packets, decode resources for decoding packets, packet processing resources, etc. These various types of receiver resources may be dynamically assigned to packets. In one design, receiver resource usage by each packet to be processed by the receiver may be estimated. The available receiver resources may be assigned to packets based on the estimated receiver resource usage by each packet and one or more assignment criteria such as priority, latency requirements, etc. The latency of each packet may be determined based on the receiver resource assignment. If the latency requirements of any packet are not met, then receiver processing may be skipped or deferred for one or more packets such that the latency requirements of each packet to be processed can be met.

    摘要： Systems, methods, and devices that facilitate finite-precision data accumulation by utilizing precision binning and queuing are provided. A precision range of a data element received into a queue can be determined. Further, a stored data element of like precision can be selected. The stored data element can be added with the data element received into the queue to generate a resultant data element. The resultant data element can be stored in a memory location or the queue as a function of like precision range.

    摘要： A pilot searcher for CDMA and GPS signals. In one aspect, the searcher is operated in conjunction with a sample buffer in a “real-time” or “off-line” mode. The writing/reading of samples to/from the buffer may be performed in a TDM manner via a common port, and samples may be decimated and packed prior to storing in the buffer. In another aspect, the overall search for pilots is partitioned into a number of tasks, with each task corresponding to a search over a given sample segment and based on a particular set of parameter values. The tasks may be stored in a queue and performed one at a time based on their order in the queue. Prior to performing a new task, the parameter values for that task is downloaded to a set of configuration registers. The parameters may be ordered and linked such that only new values are downloaded.
