System and Method for an Asynchronous Processor with Assisted Token

摘要

Embodiments are provided for an asynchronous processor using master and assisted tokens. In an embodiment, an apparatus for an asynchronous processor comprises a memory to cache a plurality of instructions, a feedback engine to decode the instructions from the memory, and a plurality of XUs coupled to the feedback engine and arranged in a token ring architecture. Each one of the XUs is configured to receive an instruction of the instructions form the feedback engine, and receive a master token associated with a resource and further receive an assisted token for the master token. Upon determining that the assisted token and the master token are received in an abnormal order, the XU is configured to detect an operation status for the instruction in association with the assisted token, and upon determining a needed action in accordance with the operation status and the assisted token, perform the needed action.

1. A method performed by an asynchronous processor, the method comprising:
receiving, at an execution unit (XU), a master token associated with a resource and further receiving an assisted token for the master token; and upon determining that the assisted token and the master token are received in an abnormal order, detecting an operation status at the XU in association with the assisted token.
