Patent number: 9465567Abstract: A method and system for printing comprises executing a formatter program on a removable Personal Computer (PC) card that controls printer controller functions of a printer. Printer formatter ready data is received from a host machine at a first interface of the removable PC card and print engine ready data is sent to the printer from a second interface of the removable PC card. A version of the formatter program is compared to a version of an updated formatter program. The updated formatter program is requested if the version of the formatter program is different than the version of the updated formatter program. The updated formatter program is downloaded from the host machine using the first interface when the second interface is coupled to the printer.Type: GrantFiled: April 18, 2011Date of Patent: October 11, 2016Assignee: Marvell International Technology Ltd.Inventors: Gary D.

Patent number: 9237250Abstract: A multifunction image processing apparatus is disclosed. The apparatus includes a communications module, a scan subsystem, a print subsystem, and a digital signal processor (DSP) block. The communications module is used to communicate with a host computer to send and receive image data files. The scan subsystem is used to scan images. The print subsystem is used to print images. The DSP block includes at least two digital signal processors. The digital signal processors can be programmed to symmetrically multiprocess portions of an image data file to process it more quickly. Alternatively, digital signal processors can be programmed to simultaneously process the image data for the scan subsystem and image data for the print subsystem.Type: GrantFiled: March 7, 2014Date of Patent: January 12, 2016Assignee: Marvell International Technology Ltd.Inventors: J.

Patent number: 9076101Abstract: A printer cable that is configured for coupling to a printer having an enclosure and a printer port. The printer cable includes a first connector for connecting to the printer port and a second connector for coupling to a host device (e.g., a personal computer (PC)). The printer cable includes a printer formatter for providing formatting services to the printer via the first connector. Since the printer formatter is integrated into the printer cable, the printer formatter is external to the printer enclosure and is easily removable and configurable by a user.Type: GrantFiled: December 19, 2012Date of Patent: July 7, 2015Assignee: Marvell International Technology Ltd.Inventor: Gary Daren Zimmerman

Patent number: 8941882Abstract: The software on the host machine examines a pixel, either alone or in relation to adjacent pixels. Based on the image data contained in the pixel or group of pixels, a multi-bit value is generated that can be used by the printing device to easily reproduce the necessary detail of the original pixel. The multi-bit value also contains print engine control parameters to handle items such as toner miser mode, toner explosion, edge roll off, etc. The multi-bit value can be generated algorithmically by using a lookup table or by some combination of these methods.Type: GrantFiled: January 29, 2013Date of Patent: January 27, 2015Assignee: Marvell International Technology Ltd.Inventors: Lyman Leonard Hall, Douglas Gene Keithley, Gary D Zimmerman, David Alan Bartle

Patent number: 8874983Abstract: A test method for an ASIC uses an embedded processor in the ASIC to execute test routines from an embedded memory or an external memory. During ASIC production, the test routines can comprehensively test of the blocks of the ASIC without a complicated test pattern from test equipment. The test routines can also perform power-up tests in systems or end products containing the ASIC. Test selection, activation, and result output can be implemented using a few terminals of the ASIC.Type: GrantFiled: October 21, 2013Date of Patent: October 28, 2014Assignee: Marvell International Technology Ltd.Inventors: Richard D Taylor, Mark D Montierth, Melvin D Bodily, Gary Zimmerman, John D Marshall
