Abstract: Incoming bit stream is processed by a single state machine into a circular buffer. Circular buffer accumulates subunits of data to form a major data unit. State machine recognizes the start of major data unit and flags the location of the major data unit in the circular buffer.

Abstract: Optical transducers disposed on an integrated circuit correspond to test points thereon. The state of optical transducers perceived by an optical sensor is correlated to test points. Alignment of the optical sensor relative to the optical transducers is accomplished electronically or mechanically.

Abstract: State of test points on an integrated circuit are encapsulated in a telemetry frame that is wirelessly conveyed to a test system. Test points may be logic levels or analog levels converted into representative multi-bit values. Conveyance off the circuit may be by radio frequency or optical emission.

Abstract: A traffic manager system coupled to a communication system for scheduling transmission of data associated with a plurality of connections in the communication system. The traffic manager includes a schedule table, a global priority queue, and a scheduler. The schedule table includes a plurality of slot locations, each having a least one tunnel entry. The scheduler is coupled to the schedule table and the global priority queue. The global priority queue has a tunnel level associated with the tunnel entry of the slot. The scheduler processes the slot locations in the schedule table and sets a tunnel active in response to processing the tunnel entry. The scheduler selects at least one connection from the tunnel level when active, which thus provides for the selection of connections from a plurality of service classes. As such, the scheduler allows per connection shaping in the tunnel mode. The scheduler, thus, maximizes communication bandwidth.
