High integrity recovery from multi-bit data failures

Methods and system for facilitating a computing platform to recover quickly from transient multi-bit data failures within a run-time data memory array in a manner that is transparent to software applications executing on the computing platform. A fault-tolerant digital computing system is provided for that utilizes parallel processing lanes in a lockstep architecture. Each processing lane includes error detectors that are configured to detect multi-bit data errors in each processing lane's memory arrays. Upon detection of a multi-bit data failure, an interrupt is generated wherein control logic software responds to the interrupt and corrects the data errors in the memory array of each processing lane.
