  • Patent number: 9143131
    Abstract: An FPGA has a number of CLBs, each CLB having a number of CABs (10, 110, 210, 310, 410). Each CAB (10, 110, 210, 310, 410) comprises: a number of configurable transistors (20, 120, 220, 320, 420) each comprising one or more useable transistors M and a number of switching transistors; and, configuration circuitry comprising a number of switching transistors. The ratio of switching transistors to useable transistors for each CAB is less than 26:1. A method of configuring such an FPGA comprises optimizing each configurable transistor.

  • Patent number: 7872770
    Abstract: A printing system includes a printer and at least one workstation operatively connected to the printer. The work station comprises at least one input/output device connecting the workstation to the printer, a controller connected to the at least one input/output device, and a memory connected to the controller. The workstation further includes an operating system, a first application, a second application, and a print driver, all residing on the memory. A first item of the first application and a second item of the second application are both receivable by the print driver. The print driver is selectively able to concatenate the first and second items into a compound print set, able to receive a selected number of copies to be printed of the compound print set entered through the at least one input/output device and able to submit the compound print set and the selected number of copies as a single print job to the printer.
