Abstract
Method and hardware apparatus are disclosed for reducing the rollback penalty on exceptions in a microprocessor executing traces of scheduled instructions. Speculative state is committed to the architectural state of the microprocessor at a series of commit points within a trace, rather than committing the state as a single atomic operation at the end of the trace.
