摘要:
The present invention relates to a user interface control for controlling the value of a variable in a processing system. The user interface control includes, a display, an input device and a processor. The processor is adapted to cooperate with the display and the input device to generate an input representation on the display, the input representation allowing the value of the variable to be specified by the user using the input device. The processor then generates a graphical representation on the display, the graphical representation showing a relationship between the variable and a parameter. Finally, the processor generates an indicator on the display, the indicator indicating a value of the parameter for the value of the variable specified using the input representation.

A method of reducing overhead for datagrams that are transmitted to or received from a serial link that reduces overhead to no more than four bytes. The datagram includes at least a Protocol Data Unit (PDU) field, a Start-of-PDU Header (SPH) field, and a SPH Control (SCH) field. The SPH and SCH fields consist of two bytes. The datagram may additionally include End-of-PDU Header (EPH) and EPH Control (ECH) fields. A method may also involve substitution of flags for subsequent headers that are identical to previous headers.
摘要:
A circuit comprises two or more chains of components, each chain comprising a plurality of components serially connected by designated pins on each component and at least one chain including one or more components of another chain, the designated pins being designated for data for one or more specific purposes. A selector is included for selecting one chain from the two or more chains over which to data is to be sent. Another circuit comprises a chain of components serially connected by designated pins on each component, and two or more controllers, each controller capable of controlling the chain for one or more of the specific purposes. A wiring board for implementing the circuit is also provided.
摘要:
A method and apparatus are provided for storing the boot configuration PROM of a microprocessor in an FPGA. The boot interface of the microprocessor, such as an I2C interface, leads to the FPGA instead of to a PROM. The boot configuration is stored as an image in the FPGA, and the microprocessor accesses the boot configuration using its normal boot interface. In this way, a dedicated boot PROM is not needed, saving real estate on the card on which the microprocessor is located. The boot configuration is also more easily modified, such as for version upgrades or diagnostics, than if the boot configuration were stored on a dedicated PROM. Different boot configurations may be stored as software images on a separate housekeeper processor, for loading into the FPGA.

摘要:
A method for incorporating a queuing device as a lossless processing stage in a network device in a communications network, comprising: monitoring a depth of a queue in the queuing device, the queue for receiving packets from an upstream device within the network device, the queuing device acting as a discard point by discarding packets when the queue is full; and, if the depth passes a predetermined threshold, sending a message to the upstream device to reduce a rate at which packets are sent to the queuing device to prevent the queue from filling and thereby preventing packet discarding and loss by the queuing device.

A method for incorporating a non-redundant component in a redundant system in a communications network, the redundant system having first and second redundant components providing first and second data streams and activity signals, respectively, the activity signals indicating which of the first and second data streams is an active data stream, the first and second data streams being unsynchronized, the method comprising: determining whether an activity switch has occurred from the activity signals; responsive to the determining, selecting an input data stream from among the first and second data streams; filtering the selected input data stream to produce an output data stream by nullifying any incorrect control information inserted into a packet in the input data stream due to the selecting; and, providing the output data stream to the non-redundant component.
