  • Method of correcting a machine check error
    Patent number: 6948094
    Abstract: Processor implementation-specific instructions save a processor state in a system memory and attempt to correct the error. Control is then transferred to processor-independent instructions. Control is returned to the processor implementation-specific instructions which then return to an interrupted context of the processor by restoring the processor state.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: September 20, 2005
    Assignee: Intel Corporation
    Inventors: Len Schultz, Nhon Toai Quach, Dean Mulla, Jim Hays, John Fu
  • Error recovery for speculative memory accesses
    Patent number: 6895527
    Abstract: A method of handling memory errors. A memory fault indication is received that is true if an error in the memory is detected while executing a memory load request to retrieve a value from the memory. A speculative load indication is received that is true if the memory load request was issued speculatively. If the memory fault indication is true and the speculative load indication is true, then an error indication that the returned value is invalid is provided, otherwise, error recovery is performed.

  • Method and apparatus for tracking bus transactions
    Patent number: 5951663
    Abstract: A method and device for tracking a bus transaction between first and second agents coupled to a bus includes issuing a request for the transaction by the first agent, storing information regarding the transaction in a buffer, and deleting the information regarding the transaction from the buffer if the first agent receives an indication that the second agent will not issue a retry.
