Abstract:
An architecture for management of vital data in a multi-module digital data processing machine, said machine comprising:predetermined maximum number of modules (M1-Mn), each of said modules (M1-Mn) including a physical nonvolatile memory (NVM1-NVMn) in which said vital data are stored, each of said physical nonvolatile memories (NVM1-NVMn) including: first memory location areas (G1-Gn), and second memory location areas (L1-Ln), wherein said first memory areas (G1-Gn) are adapted to store global vital data associated with operation of the machine, said global vital data being replicated from one physical nonvolatile memory to another and identical when all the modules are in a correct operational state, and wherein said second areas (L1-Ln) are adapted to store vital local data associated with operation of respective modules (M1-Mn) in which said local physical nonvolatile memory is disposed.
