Abstract:
A computer architecture allows for simplified recovery after mis-speculation during speculative execution by controlling speculation to occur within idempotent regions that may be recovered by re-execution of the region without the need for restoring complex state information from checkpoints. A compiler for increasing the size of idempotent regions is also disclosed.
