LOW OVERHEAD EXCEPTION CHECKING

摘要

Exception detection is expedited in virtual machine interpreter (VMI) accelerator hardware (120) by dispatching fetched bytecodes along with instructions that cause a processor interrupt if the fetched bytecodes cause an exception to be thrown. The processor interrupt serves to indicate to the VMI (120) that an exception condition exists, thereby obviating the need to for the VMI (120) to wait for the result of an exception check to be sent from the CPU (110) to the VMI (120).
