Abstract: A mesh receiver has a wakeup receiver for reception of a wakeup sequence formed by keyed RF or a sequence of wireless packets and gaps, a transmitter forming low speed RF wakeup sequence to other mesh stations, a mesh receiver for reception of high speed WLAN packets, the transmitter sending a wireless ACK packet in response to a wakeup sequence, the mesh receiver thereafter receiving wireless packets from a remote station, the mesh transmitter sending an ACK, the mesh station thereafter identifying a next hop station, and sending a wakeup sequence to that station, after receipt of an ACK, sending the data, the mesh receiver and mesh transmitter thereafter going to sleep.

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.

Abstract: A communications processor is operative in a plurality of modes including at least a high performance mode, a power savings mode with lower computational capability, and a shutdown mode with a wakeup capability. A memory for the communications processor has a high speed segment and a low speed segment, the high speed segment and low speed segment respectively on a high speed data bus and a low speed data bus, the high speed data bus and low speed data bus coupled by a bidirectional bridge.

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.

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.

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.
