  • Publication number: 20210119734
    Abstract: In accordance with embodiments, methods for data communications are disclosed. A device obtains a forward error correction (FEC) encoded bit stream. The device maps the FEC encoded bit stream to produce a set of symbols according to a bit-to-symbol mapping rule. The bit-to-symbol mapping rule comprises a first mapper bit position associated with a first mapper error protection level and a second mapper bit position associated with a second mapper error protection level. The first mapper error protection level is greater than the second mapper error protection level. The device then transmits the set of symbols in the communications system.

  • Patent number: 9218234
    Abstract: Systems and methods for executing a memory dump in a computer system are provided. A trigger event is detected in the computer system. The computer system is configured to detect both a kernel panic and a system hang and to execute memory dump if either of the kernel panic or the system hang is detected. The memory dump is executed in the computer system in response to the detecting of the trigger event. The executing of the memory dump includes storing a current context of the computer system in a portion of a memory device. The current context is stored without reserving the portion prior to the detecting of the trigger event. The computer system is restarted and a bootstrap program is executed, where a running space of the bootstrap program is restricted to the portion of the memory device. The bootstrap program is used to upload the current context to a host device.
