ABSTRACT:
Systems and methods for redundancy management in fault tolerant computing are provided. The systems and methods generally relate to enabling the use of non-custom, off-the-shelf components and tools to provide redundant fault tolerant computing. The various embodiments described herein, generally speaking, use a decrementer register in a general purpose processor for synchronizing identical operations across redundant general purpose processors, execute redundancy management services in the kernels of commercial off-the-shelf real-time operating systems (RTOS) running on the general purpose processors, and use soft coded tables to schedule operations and assign redundancy management parameters across the general purpose processors.
