A wireless recharging system and method in which, by means of direct optical coupling, a matrix of coils and their respective LED lights or lasers interact transmitting and receiving light pulses and wireless power bursts in a fast control loop scheme, allowing precise current control and efficient energy transmission rates with integrated optical data communications in the same interface. An alignment mechanism in which in the matrix of coil transmitters only those receiving direct pulsed light are activated, keeping other coils off, extending the active charging surfaces and improving the overall efficiency, avoiding the requirement of precisely positioning wireless power receptors. A range of power transmission rates and the possibility of recharging different devices with different power requirements simultaneously while laying on top of the charging surface, acting also as an optical communication hub. Charging of vehicles while in motion due to the fast responsiveness of the optical communication.

A multi-streaming processor has a plurality of streams for streaming one or more instruction threads, a set of functional resources for processing instructions from streams, and interrupt handler logic. The logic detects and maps interrupts and exceptions to one or more specific streams. In some embodiments, one interrupt or exception may be mapped to two or more streams, and in others two or more interrupts or exceptions may be mapped to one stream. Mapping may be static and determined at processor design, programmable, with data stored and amendable, or conditional and dynamic, the interrupt logic executing an algorithm sensitive to variables to determine the mapping. Interrupts may be external interrupts generated by devices external to the processor software (internal) interrupts generated by active streams, or conditional, based on variables. After interrupts are acknowledged, streams to which interrupts or exceptions are mapped are vectored to appropriate service routines.

A multi-streaming processor has a plurality of streams for streaming one or more instruction threads, a set of functional resources for processing instructions from streams, and interrupt handler logic. The logic detects and maps interrupts and exceptions to one or more specific streams. In some embodiments, one interrupt or exception may be mapped to two or more streams, and in others two or more interrupts or exceptions may be mapped to one stream. Mapping may be static and determined at processor design, programmable, with data stored and amendable, or conditional and dynamic, the interrupt logic executing an algorithm sensitive to variables to determine the mapping. Interrupts may be external interrupts generated by devices external to the processor software (internal) interrupts generated by active streams, or conditional, based on variables. After interrupts are acknowledged, streams to which interrupts or exceptions are mapped are vectored to appropriate service routines. In a synchronous method, no vectoring occurs until all streams to which an interrupt is mapped acknowledge the interrupt.

A multi-streaming processor has a plurality of streams for streaming one or more instruction threads, a set of functional resources for processing instructions from streams; and interstream control mechanisms whereby any stream may effect the operation of any other stream. In various embodiments the interstream control mechanisms include mechanisms for accomplishing one or more of enabling or disabling another stream, putting another stream into a sleep mode or awakening another stream from a sleep mode, setting priorities for another stream relative to access to functional resources, and granting blocking access by another stream to functional resources. A Master Mode is taught, wherein one stream is granted master status, and thereby may exert any and all available control mechanisms relative to other streams without interference by any stream. Supervisory modes are taught as well, wherein control may be granted from minimal to full control, with compliance of controlled streams, which may alter or withdraw control privileges. Various mechanisms are disclosed, including a mechanism wherein master status and interstream control hierarchy is recorded and amended by at least one on-chip bit map. In this mechanism each stream maintains and edits a bitmap granting or withdrawing control privileges for each other stream, the settings valid for any stream but a Master stream, which will ignore the settings.

In a data-packet processor, a configurable queuing system for packet accounting during processing has a plurality of queues arranged in one or more clusters, an identification mechanism for creating a packet identifier for arriving packets, insertion logic for inserting packet identifiers into queues and for determining into which queue to insert a packet identifier, and selection logic for selecting packet identifiers from queues to initiate processing of identified packets, downloading of completed packets, or for requeuing of the selected packet identifiers.

Queueing system for processors in packet routing operations

A background event buffer manager (BEBM) for ordering and accounting for events in a data processing system having a processor includes a port for receiving event identifications (IDs) from a device, a queuing function enabled for queuing event IDs received, and a notification function for notifying the processor of queued event IDs. The BEBM handles all event ordering and accounting for the processor. The BEBM in preferred embodiments queues events by type with priority and by priority within type, and also handles sending acknowledgement to the device when processing on each event is concluded, and buffers the acknowledgement process. In particular embodiments the apparatus and method is taught as a packet processing router engine.

A dynamic multistreaming processor has instruction queues, each instruction queue corresponding to an instruction stream, and execution units. The dynamic multistreaming processor also has a dispatch stage to select at least one instruction from one of the instruction queues and to dispatch the selected at least one instruction to one of the execution units. Lastly the dynamic multistreaming processor has a queue counter, associated with each instruction queue, for indicating the number of instructions in each queue, and a fetch counter, associated with each instruction queue, for indicating an address from which to obtain instructions when the associated instruction queue is not full. The dynamic multistreaming processor might also have fetch counters for indicating a next instruction address from which to obtain at least one instruction when the associated instruction queue is not full. The dynamic multistreaming processor could also have a second counter for indicating a next instruction address.

A background memory manager (BMM) for managing a memory in a data processing system has circuitry for transferring data to and from an outside device and to and from a memory, a memory state map associated with the memory, and a communication link to a processor. The BMM manages the memory, determining if each data structure fits into the memory, deciding exactly where to place the data structure in memory, performing all data transfers between the outside device and the memory, and maintaining the memory state map according to memory transactions made, and informing the processor of new data and its location. In preferred embodiments the BMM, in the process of storing data structures into the memory, provides an identifier for each structure to the processor. The system is particularly applicable to Internet packet processing in packet routers.
