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： 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.
摘要翻译：用于CDMA和GPS信号的导频搜索器。在一个方面，搜索器与“实时”或“离线”模式中的采样缓冲器结合操作。可以通过公共端口以TDM方式执行对/从缓冲器的读取/从缓冲器的读取/读取，并且可以在存储在缓冲器中之前对样本进行抽取和打包。在另一方面，对导频的总体搜索被划分成多个任务，其中每个任务对应于在给定采样段上的搜索，并且基于特定的一组参数值。任务可以存储在队列中，并根据队列中的顺序一次执行一次。在执行新任务之前，将该任务的参数值下载到一组配置寄存器。可以对参数进行排序和链接，以便仅下载新值。

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.
