  • Patent number: 7941781
    Abstract: A system and method of testing IP cores contained in a system-on-chip integrated circuit is disclosed. An operation command is received on an input/output port of the circuit. The operation command includes an operation code component, data component(s), and expected time component. The received operation command is processed to supply test data to each of the IP cores being tested. Result data is received in response to the supplied test data from each of the IP cores being tested. The result data is processed and from the processed result data is generated a status data packet. The status data packet includes the operation code component and a status flag component and is provided on the input/output port.

  • Patent number: 7755659
    Abstract: A laser printer for Braille that obviates the need for embossing mechanisms and specialized paper. A laser printer for Braille according to the present teachings increases an amount of a toner that adheres to an area of a paper that corresponds to the Braille element. The increased amount of toner yields a printed Braille element that may be read by touch.

  • Patent number: 7648903
    Abstract: A semiconductor die includes a plurality of drivers and a plurality of bonding pads. Each driver is formed by a plurality of interconnected modules and has an associated bonding pad to which at least one of the modules of the driver is electrically connected. The modules of some of the drivers are positioned outside of the associated bonding pad toward a periphery of the die. The bonding pads may be arranged, for example, in a double- or triple-staggered pattern around the periphery of the die.

  • Patent number: 7401315
    Abstract: A method for implementing package-level intellectual property (PLIP) preverification for system on chip (SOC) devices includes providing at least one externally connected intellectual property (IP) core with an SOC. A package generic unit is provided with the IP core and is configured for providing external interface functions with respect to the SOC, wherein said package generic unit is pre-verified in silicon and independent of the specific packaging of the SOC. A package adaptation unit is provided with the IP core and is configured for providing external interface functions with respect to the SOC, wherein the package adaptation unit is pre-verified in silicon and dependent upon the specific packaging of the SOC.

  • Patent number: 7281178
    Abstract: A system and method for write-enable bypass testing in an electronic circuit. According to one embodiment, the integrated circuit that includes a memory block having at least one input and at least one output. At least one input is associated with a block of input logic and at least one output is associated with a block of output logic. The integrated circuit also includes a test circuit coupled to the memory block and operable to verify the block of input logic and the block of output logic while at the same time not impacting the timing of the integrated circuit. As such a signal propagating through just the input logic, the memory block and the output logic does so in an amount of time substantially similar the time it takes to propagate through the input logic, the memory block, the output logic, and the test circuit.

  • Patent number: 6862375
    Abstract: A multifunction image-transfer system with printing, scanning, digital copying, and facsimile capabilities detects skew as sheet media is fed. A skew processor digitally skews image data as a function of sheet-feed skew detected by skew detectors. In the context of a scanning operation, an image-bearing document is fed to a scanner device, which generates a digital raster image. A buffer stores portions of the digital image as it is transferred. The image data in the buffer is digital skew-compensated before it is transferred to a host computer. In the context of a printing operation, raster print data is stored in the memory buffer and then skew compensated before the image is printed to the print media. The digital skew compensation allows mechanical tolerances in such systems to be relaxed and system lifetimes to be lengthened since “true” images can result despite moderate media skew.

  • Patent number: 6549962
    Abstract: A demonstration page system in an apparatus including a recycling internal memory device is provided. Demonstration page information is stored in the recycling internal memory device. An output device is provided to output a demonstration page. A user interface is also provided. The user interface is adapted and constructed to selectively retrieve demonstration page information from the recycling internal memory device and send the demonstration page information to the output device to be output. The recycling internal memory device can be provided as non-volatile RAM, such as Flash memory. When the apparatus is a multi-function peripheral including fax capabilities, the demonstration page information can be stored in fax storage memory. An overwrite mechanism can be provided to write over the demonstration page info stored in the recycling internal memory device when the multi-function peripheral receives its first fax. The overwrite mechanism can be embedded in firmware associated with the apparatus.

  • Patent number: 6334160
    Abstract: There is disclosed a configuration for multiplexing the USB signals onto the IEEE 1284 signals thereby allowing a single connector on the device to support either protocol. Within the device, each protocol block is connected to transceiver to compensate for differences in driver/receiver characteristics for the protocol. The outputs of the transceivers are connected to a signal conditioner to allow proper selection of termination impedance. A controller senses whether a passive adapter is attached to the connector. When the passive adapter is not connected the controller selects the 1284 protocol and its associated transceiver and signal conditioning. If the passive adapter is connected, the controller selects the USB protocol and its associated transceiver and signal conditioning. The passive adapter connects pre-selected pins on the device's connector to a USB connector. There is also described an arrangement to allow the passive adapter and device to provide USB hub functions.
