Abstract

Exception handling systems and techniques for handling exceptions and sequencing conflicts in an asynchronous processor. Two designated queues are used to respectively keep program counter values of instructions and the assignments of the execution units for executing the instructions according to the program order. An asynchronous circuit is coupled between the program counter unit and the write-back unit of the processor to provide asynchronous communications.
