Latest Patents
Walter Patrick Christmas holds a patent for a "Selective memory duplication arrangement." This invention involves an active-standby dual processor that performs selective memory duplication through both hardware and the operating system. The system utilizes a page table that stores a shadowing flag for each memory page of the active memory of the processor. This flag indicates whether the corresponding page is shadowed. When memory is allocated to a process, the operating system checks the process's data statement for shadowing indications. If shadowing is required, the allocated page's shadowing flag is set. The invention ensures that when the active processor writes to its memory, the page table controller checks the shadowing flag. If the flag is set, the write is replicated on the standby processor's memory, enhancing data integrity and reliability.
