METHOD AND APPARATUS FOR MAINTAINING CONTEXT WHILE EXECUTINGTRANSLATED INSTRUCTIONS

摘要

A method (fig. 1) of maintaining translation context for instructions translated from instructions designed for a target microprocessor to run on a host microprocessor including storing translation context related to each translated host instruction, indicating a translation context for host instructions presently being executed by the host processor, comparing (fig. 2) translation context stored for a next host instruction with the translati on context for a host instruction presently being executed, executing the next host instruction if the translation context of the next host instruction and the presently executing host instruction compare, and searching (fig. 2) for an instruction with translation context which compares to the translation context of the host instruction presently executing if the translation conte xt of the next host instruction and the presently executing host instruction do not compare.
