A source driver for a display device includes a gamma voltage generation circuit, first through (2m)-th data driving circuits, and a switch circuit. The gamma voltage generation circuit generates R, G and B gamma voltages. The (2k&#x2212;1)-th data driving circuits consecutively receive red image data and blue image data, and consecutively generate a R driving voltage and a B driving voltage using the R gamma voltages and B gamma voltages, respectively, during one horizontal period. The (2k)-th data driving circuits consecutively receive first green image data and second green image data, and consecutively generate a G1 driving voltage and a G2 driving voltage, respectively, using the G gamma voltages during the one horizontal period. The switch circuit outputs the R, B, G1, and G2 driving voltages through different data lines from each other based on a first selection signal and a second selection signal.

Display source driver

An electronic device includes a first processor; and a second processor; and a third processor. The second processor is configured to detect an event, select one of the first and third processors to perform one or more operations associated with the event, and cause the selected processor to perform the one or more operations.

Multi-processor device

In a method and apparatus for modifying an error in the case of one-bit error in a parallel digital bus, the original data can be recovered when one of the data bits is fixed as '0' or '1' because of a hardware error, or when one of the data bits has a random value of &lsquo;0&rsquo; or &lsquo;1&rsquo;. In case of no error, the present invention only endures such overhead as propagation delay, rarely causing a decrease in performance. If the present invention is chosen as a bus specification, such as PCI (in other words, if the present invention is utilized as a bus interface in the bus-using chips), the bus fault tolerance is improved.

Apparatus and method for correcting one-bit error of parallel digital bus

An apparatus and method for guaranteeing the integrity of a PCI bus is disclosed. Multiple general purpose computers are connected using the PCI bus, and the PCI bus signals between or among them are compared. The present invention comprises general purpose computers, PCI monitoring cards, and network lines. An apparatus and a method for detecting faults are provided without adopting an exclusive CPU board or input/output bus to detect faults. A PCI monitoring card is appended to each general purpose computer system, and the computer systems are connected to electronic communication media.
