  • Publication number: 20110083059
    Abstract: A selection-signal generating circuit in an LSI being a transmission-side LSI, when a transmission error is detected on an A-side signal line and degeneration control is performed thereon, instructs a selector to select an input from an ECC generator in order to transmit data and ECC data for this data to be transmitted via the B-side signal line, via the A-side signal line. In this manner, the degenerated signal line is used to transmit the ECC data for transmission data to be transmitted via a signal line which is not degenerated.

  • Publication number: 20110072296
    Abstract: A clock adjustment circuit delays a phase of a clock signal on the basis of a TAP value so as to output an adjusted clock signal. By synchronizing transmission data with the adjusted clock signal, reception data is generated. A data adjustment circuit delays the transmission data on the basis of a TAP2 value. By synchronizing the delayed transmission data with the adjusted clock signal, adjusted reception data is generated. A data adjustment control circuit generates the TAP2 value on the basis of a result of a comparison between the reception data and the adjusted reception data, and outputs to a clock adjustment control circuit an instruction to update the TAP value.
