Abstract
A processor may include an address monitor table and an atomic update table to support speculative threading. The processor may also include one or more registers to maintain state associated with execution of speculative threads. The processor may support one or more of the following primitives: an instruction to write to a register of the state, an instruction to trigger the committing of buffered memory updates, an instruction to read the a status register of the state, and/or an instruction to clear one of the state bits associated with trap/exception/interrupt handling. Other embodiments are also described and claimed.
