Adaptive FEC codeword management
Adaptive FEC coding is used to adjust the codeword composition of FEC codewords in a communication system. A codeword composition ratio may be adjusted in response to variance of a measured transmission error value from a target transmission error value in the system.

A computing machine comprises an electronic circuit operable to perform a function, a programmable integrated circuit such as an FPGA, and a processor.

System and method for optimizing branch logic for handling hard to predict indirect branches
A system and method for optimizing the branch logic of a processor to improve handling of hard to predict indirect branches are provided. The system and method leverage the observation that there will generally be only one move to the count register (mtctr) instruction that will be executed while a branch on count register (bcctr) instruction has been fetched and not executed. With the mechanisms of the illustrative embodiments, fetch logic detects that it has encountered a bcctr instruction that is hard to predict and, in response to this detection, blocks the target fetch from entering the instruction buffer of the processor. At this point, the fetch logic has fetched all the instructions up to and including the bcctr instruction but no target instructions. When the next mtctr instruction is executed, the branch logic of the processor grabs the data and starts fetching using that target address. Since there are no other target instructions that were fetched, no flush is needed if that target address is the correct address, i.e. the branch prediction is correct. |

Another example of a current state in which a mapping can be reused is adjacent program instructions having mutually exclusive condition codes and sharing a destination register such that only one of those adjacent instructions will ever be executed. |

Remote copy network
A remote copy network realizes low-cost multi-hop remote copying. Remote copying is executed via a remote copy network (RCN) having a source edge device connected to a source storage and a target edge device connected to a target storage.

The source edge device receives remote copy I/O from the source storage, creates a log entry to which a sequential number is added, and sends the log entry to a target edge device. The target edge device acquires the remote copy I/O from the received log entry, and sends the remote copy I/O to the target storage in the order of the sequential number. |

Cached reads for a storage system
Embodiments of the invention may improve read operations for fully cached workloads on storage systems with limited processing or CPU-cache resources. Some embodiments employ an indicator such as a counter to indicate when the use of readahead analysis steps, such as resource, intensive predictive processing, is undesirable. In these embodiments, the counter is incremented for each buffer cache read that is successfully performed without the need for a disk input/output operation. When the counter variable exceeds a threshold such as, for example, a maximum readahead size, then the system advantageously foregoes predictive processing steps of the readahead analysis phase, and further foregoes a readahead execution phase. The foregoing results in a net performance benefit for the system based on a reduced likelihood of a need for an input/output operation, and further, based on a reduced likelihood of a need for predictive processing relating to readahead analysis and/or execution. |

The apparatus measures the average intensity of the detected light ray in the wavelength band and the intensity of the detected light ray at the particular wavelength to determine an occurrence of leak when the ratio of the intensity at the particular wavelength to the measured average intensity in the wavelength band is lower than a predetermined reference value. Variations in human body or physical condition affect the whole of the wavelength band but have no effects on the relative relationships between the wavelength band and the particular wavelength. Thus, the leak of the liquid can be detected without being affected by variations in human body or physical condition. |

Scan driving circuit and organic light emitting display using the same
A scan driving circuit including an input terminal to receive an input signal or a voltage output from a previous stage; first and second clock terminals to receive first and second clock signals having phases inverted to each other and partially overlap at a high level, respectively; and a plurality of stages having an output terminal to output scan signals having a low level in sequence, leaving an interval between the scan signals, equivalent to a time the first and second clock signals overlap at the high level, wherein the output terminal of the stage is maintained to have a non-floating state regardless of whether the stage outputs the scan signal. |

Light emitting device and electronic appliance
It is an object of the present invention to provide a light emitting device which can be made into a module with smaller volume. By using a light emitting element represented by an EL element and the like as a pixel portion, two pixel portions are formed at different portions over the light emitting device. A first pixel portion comprises a plurality of pixels arranged in matrix. In the periphery of the first pixel portion, a first source line driving circuit and a first gate line driving circuit for transmitting signals to the first pixel portion are formed. A second pixel portion is formed of passive pixels, and segregated from a TFT group which constitutes the first pixel portion, the first source line driving circuit, and the first gate line driving circuit in the direction from the back surface of the substrate to the top surface of the substrate by interposing an interlayer film therebetween. |

Driving system and method for an electroluminescent display
A driving system and method for electroluminescent displays which by connecting the electroluminescent elements that have been lighted up to the electroluminescent elements that are to be lighted up causes charge to be shared among the elements, so as to increase the voltage level at the anodes of the electroluminescent elements which are to be lighted up, thereby reducing the power consumption and increasing the response speed. |

Display apparatus
Apparatus for compensating for a threshold voltage of a driver element having gate and drain electrodes which controls current flowing in a light emitting element effective in an on and off state. A capacitor is disposed between the gate electrode and a drain electrode when the light emitting element is in the on state emits light and when the light emitting element is in the off state, applying a voltage to the gate and the source of the driver element and a threshold voltage between the gate and drain electrodes is detected and stored in the capacitor, by writing a signal voltage closer to a potential which causes the driver element to turn off than the potential supplied to the gate electrode of the driver element when detecting a threshold value, the signal voltage being superimposed on the threshold voltage without losing the threshold voltage of the driver element. |
