摘要:
In one embodiment, a network device is disclosed. For example, in one embodiment of the present invention, the device comprises a processor and a core memory having a receive buffer and a transmit buffer. The device comprises a bus coupled to the processor and the core memory. The device comprises at least one co-processor coupled to the core memory via a direct link, wherein the at least one co-processor is capable of accessing at least one of: the receive buffer, or the transmit buffer, without assistance from the processor.

A DSP device is disclosed having multiple DMA controllers with global DMA access to all volatile memory resources in the DSP device. In a preferred embodiment, each of the DMA controllers is coupled to each of the memory buses and is configured to control each of the memory buses. A memory bus multiplexer may be coupled between the subsystem memory bus and each of the DMA controllers, and an arbiter may be used to set the memory bus multiplexer so as to allow any one of the DMA controllers to control the memory bus. The memory bus may also be controlled by the host port interface via the memory bus multiplexer. A round-robin arbitration technique is used to provide each of the controllers and the host port interface fair access to the memory bus. This approach may advantageously provide increased flexibility in the use of DMA controllers to transfer data from place to place, with only a minimal increase in complexity.

In a digital processing unit having a plurality of digital signal processors, a first digital signal processor can request a direct transfer of a signal group stored in the memory unit of a second digital signal processor. In order to insure that the second digital signal is active, a control signal is generated by the direct memory access controller of the first digital signal processor. The control signal is applied the directly to the memory access controller of the second digital signal processor. When the second digital signal processor is in an IDLE mode, the control signal activates the second digital signal processor.

A signal detector for receiving a wide band (W) of frequency-hopped signals which channelizes the incoming signals, via filter banks into a plurality (L) of channels. Magnitude squaring circuits in each channel generate a "power" estimate which is compared to a preset threshold value by threshold-quantizer units that produce a positive voltage (=1) if the threshold is exceeded. After summation of all the channels, the direct sequence (DS) signal component and noise component are processed so that a DC voltage is produced if a frequency-hop signal (FH) is present which is greater in value than when the signal is not present. Thus the DC signal indicates whether the FH signal is present or absent.

A narrowband parameter estimator circuit is described which can be used to estimate the frequency and the relative power of narrowband interference tones which reside in a wideband information signal. A two-weight adaptive filter with a phase/frequency-lock loop circuit works in conjunction with a stepped synthesizer to lock onto the individual narrowband interference tones. A lock-detect circuit signals a digital logic unit to record the frequency of the stepped synthesizer and to measure the power in the adaptive filter output signal. This same output signal is used to cancel the unwanted tone in the wideband information signal being transmitted.

A tray having at least one sidewall having a top edge, an interior surface, an exterior surface, and a bottom surface adjacent to the sidewall. The bottom surface and the interior surface combine to form a product receiving space of the tray. The tray has an injection-molded feature having an anchor portion and a flange portion. The anchor portion is adjacent the interior surface of the at least one sidewall, and the flange portion extends from the anchor portion and is adjacent the top edge of the at least one sidewall.

A cutlery dispenser comprises a storage chamber adapted to retain a plurality of cutlery therein; an ejector for sequentially ejecting the plurality of cutlery from the storage chamber; an actuator for driving the ejector; and a sensor for triggering the actuator in response to an event.
摘要:
The present invention relates to dispensers for disposable cutlery. The invention also relates to pluralities of disposable cutlery that can be used in the cutlery dispenser of the present invention, as well as other cutlery dispensers that do not use a cartridge therein. The present invention also relates to disposable cutlery that has been adapted to make it better suited to stacking, such as for use in cutlery dispensers that do not include a cartridge.
