摘要： A circuit selectively extracts bits from different locations from a source register and loads them in logical order in one side of a destination register. The register is divided into subsets. All of the transfer bits in each subset are arranged on one side and in logical order. These subsets are paired. The bits from one pair are shifted by an amount equal to the non-transfer bits from the other pair and then combined with the bits from the other pair to form a new group of bits that are on one side and are in logical order. The process of shifting bits of one of a pair of groups and combining with the other of the pair continues until all of the transfer bits from the source register are in one group on one side and in logical order.

摘要： A system for synchronizing and re-ordering data transmitted between first and second clock domains associated with first and second device interfaces, respectively, includes a splitter, an arbiter, a transaction manager, and a read data buffer. The splitter receives a parent read request from one or more data input ports of the first device interface and splits it into one or more read requests. The arbiter receives the one or more read requests and selects one of the read requests and transmits it to the transaction manager. The transaction manager allocates an entry to the read request and then the read request is transmitted to the read data buffer. Thereafter, the read data buffer transmits the read request to the second device interface and transmits received response data to the first device interface.

摘要： A processor device processes data samples of a radio signal in a mobile communication system. A fast flow process is executed for all samples and a batch process is executed at intervals on a subset of the samples. The device has a processor for executing the flow process via a local buffer memory, a memory interface to a system memory, and a memory controller for controlling storing of the data samples in the buffer memory. The processor establishes whether data samples in the local buffer memory are part of the subset, and if not, invalidates them after executing the flow process. The memory controller provides free memory space in the local buffer by transferring data samples which are not invalidated from the local buffer memory to the system memory, and by invalidating processed samples. Advantageously the local buffer may be relatively small, while the amount of data transferred to the system memory is limited.
