  • Publication number: 20240397368
    Abstract: A multi-thread communication system has several communications processors operative over a single interface for transmitting and receiving packets. The multi-thread communications processor is operative to sequentially handle multiple thread processes for each communications processor on a cycle by cycle basis according to a thread map register which determines the order of execution and how many cycles of a particular thread occur during a canonical interval.

  • Patent number: 12045645
    Abstract: A communication processor is operative to adapt the thread allocation to communications processes handled by a multi-thread processor on an instruction by instruction basis. A thread map register controls the allocation of each processor cycle to a particular thread, and the thread map register is reprogrammed as the network process loads for a plurality of communications processors such as WLAN, Bluetooth, Zigbee, or LTE have load requirements which increase or decrease. A thread management process may dynamically allocate processor cycles to each respective process during times of activity for each associated communications process.

  • Patent number: 11916679
    Abstract: A bitstream modifier is operative on a packet which uses repetition coding. The bitstream modifier increases randomness of the data in a deterministic manner such that spectral spurs from repetition coding are greatly reduced, thereby providing greater available transmit power. In another example of the invention, baseband samples of a header and/or payload for a Bluetooth packet are modified by a canonical sequence with a low slew rate for data such that the variations in frequency may be tracked by a receiver and the transmitted spectral spurs reduced.

  • Patent number: 11893249
    Abstract: The present invention is an controller for dynamically allocating RAM between powersave code copied from ROM and transient RAM memory used for storing packets. When the utilization of the transient RAM memory is low, code segments are copied from ROM and executed from RAM using a RAM pointer table which is updated after the code segments are copied over from ROM, and when the utilization of the transient RAM memory is high, code segments are deallocated from RAM and the pointer table is updated to point to the corresponding location in flash ROM.

  • Patent number: 11775306
    Abstract: A multi-thread processor has a canonical thread map register which outputs a sequence of thread_id values indicating a current thread for execution. The thread map register is programmable to provide granularity of number of cycles of the canonical sequence assigned to each thread. In one example of the invention, the thread map register has repeating thread identifiers in a sequential or non-sequential manner to overcome memory latency and avoid thread stalls. In another example of the invention, separate interrupt tasks are placed on each thread to reduce interrupt processing latency.

  • Patent number: 11537190
    Abstract: A task processor has a low power connectivity processor and a high performance applications processor. Software processes have a component operative on a connectivity processor and a component operative on an applications processor. The low power connectivity processor is coupled to a low power front end for wireless packets and the high performance applications processor is coupled to a high performance front end. A power controller is coupled to the low power front end and enables the applications processor and high performance front end when wireless packets which require greater processing capacity are received, and removes power from the applications processor and high performance front end at other times.
