A system and method for providing a fault-tolerant basis to execute instructions is disclosed. The system comprises an error detector, a rewriting module, a recovery engine, a fault locator and a fallback programming module. The error detector detects a first error in the execution of an instruction in a faulty stage unit of a first pipeline unit. The rewriting module rewrites the instruction to form a rewritten instruction responsive to detecting the first error. The recovery engine executes the rewritten instruction in the first pipeline unit. The error detector determines if a second error occurs in the execution of the rewritten instruction. Responsive to detecting the second error, the recovery engine selects a substitute stage unit for the faulty stage unit from a second pipeline unit. The fault locator locates a faulty component for the faulty stage unit. The fallback programming module establishes a fallback unit for the faulty component. |
