  • Publication number: 20130272454
    Abstract: A data receiving circuit includes a generating unit that generates multiple clocks with different phases from one another. The data receiving circuit includes multiple acquiring units that acquire data from a received data signal by using different clocks from one another out of the multiple clocks generated by the generating unit. The data receiving circuit includes a determining unit that determines whether the data acquired by the multiple acquiring units are consistent. The data receiving circuit includes a correcting unit that corrects the phases of the multiple clocks in a direction in which data inconsistency does not occur when the determining unit has determined that there is data inconsistent with the other data in the data acquired by the multiple acquiring units.

  • Patent number: 8436644
    Abstract: A configuration method performs a configuration of a FPGA circuit by setting configuration data from a configuration circuit to the FPGA circuit. The method counts, within the FPGA circuit, a number of times a configuration of the FPGA circuit fails. The method adjusts, within the FPGA circuit, the configuration data at a time when the configuration failed if the counted number exceeds an upper limit value, and re-executes the configuration based on the adjusted configuration data. The method sets the configuration data in which the configuration is succeeded from the FPGA circuit to the configuration circuit when the configuration is successful.
